Crash on Lion #370

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Since upgrading to Lion, MacVim has gone from never crashing to crashing almost 
daily.

My two colleagues that use MacVim have both also had frequent crashes since 
upgrading to Lion.

I got crashes both on my old MacBook that was upgraded to Lion from a Snow 
Leopard installation that already had MacVim 7.3 (55) installed, and on my new 
MacBook Air that came with Lion (now at 10.7.1), and where I installed MacVim 
7.3 (61).

MacVim was installed through homebrew in both cases.

I'm afraid I haven't yet figured out what steps reproduce it, and it's 
infrequent enough (0 to 3 times a day or so) that I can't realistically try 
turning parts of my dotfiles/plugins off and see when it stops.

I'll update this ticket with the output from any future crashes if you don't 
mind. This is the one that happened just now. Crash log attached.

And the below was the terminal output. saveScreenState is from NERDTree, but I 
assume these are errors that are due to the crash, not the cause of it. I tried 
toggling the NERDTree several times to trigger those functions and that did not 
replicate the crash.

    Vim(9846,0x7fff74877960) malloc: *** error for object 0x7fa1ea812c08: incorrect checksum for freed object - object was probably modified after being freed.
    *** set a breakpoint in malloc_error_break to debug
    Vim: Caught deadly signal ABRT
    Vim: preserving files...
    Error detected while processing function <SNR>26_saveScreenState..<SNR>26_putCursorInTreeWin..<SNR>26_exec:Vim: Finished.

    line    3:
    E523: Not allowed here: 1wincmd w
    Press ENTER or type command to continue

I understand this might not be enough to go by to do anything. Please let me 
know if you can think of anything I can do to help track this down.

On my old computer, MacVim rarely if ever crashed on Snow Leopard, but the same 
installation of MacVim sometimes crashed several times on the same day after 
updating to Lion.

I didn't however start seeing the crashes until after a month or so with Lion, 
when I started using it for full-time work and not just infrequent side 
projects. Not sure if that means the problem was introduced with 10.7.1, some 
changes in my dotfiles (my colleagues use very similar dotfiles), or just by 
using MacVim a lot more.

Found a crash log from two days ago that looks near identical.

Again. This time EXC_BAD_ACCESS (SIGSEGV) instead of EXC_CRASH (SIGABRT).

It looks like it is core Vim that is crashing.  This could be one of two 
reasons: 1) something changed in Lion to cause this, or 2) some new patch to 
Vim is causing this.  (At this point in time I would guess it is the second 
option.)

I just merged the very latest Vim patches to master, so before we do anything 
else please clone the MacVim repo on GitHub and build from that [1] (Homebrew 
won't have the latest patches).  It is possible that the bug has already been 
fixed so lets rule out that possibility before taking this up with the Vim devs.

Björn, thanks.

"** BUILD SUCCEEDED **" but crashes on launch. See log. I built with the exact 
commands and flags from https://github.com/b4winckler/macvim/wiki/Building.

It has linked against a different Ruby version than what your plugins use.  Try 
supplying the --with-ruby-command flag to the configure script.  E.g.

./configure --with-ruby-command=/usr/local/bin/ruby

(substitute with the path to your custom Ruby, wherever that is, "which ruby" 
may be the one to use, I'm not sure).

GoogleCodeExporter commented 9 years ago 
Björn, thanks again. I use RVM (http://beginrescueend.com/), so I had to do 
"rvm use system" to use system Ruby before building. Or I could have passed it 
in with "--with-ruby-command" I suppose.

It built successfully, so I'll report back if it crashes or goes a few days 
without crashing.

Hmmm...it looks suspiciously like there is still some problem with the Ruby 
support on Lion. I patched a critical Ruby bug a while ago thinking I had fixed 
all problems, but maybe there are still problems.

For the moment all I can say is try running without any plugins that use Ruby. 
It would be interesting to see if Vim stops crashing then.

Which Ruby plugins are you using? I might have to install them myself and see 
if I can reproduce.

What were you doing when this last crash happened? Looks like you were opening 
a file in a split view or something?

GoogleCodeExporter commented 9 years ago 
Thanks. I compiled it against system Ruby (1.8.7), but I use another Ruby 
(1.9.3) usually, and ":!which ruby" in MacVim will say 1.9.3. Not sure if that 
plays into it.

The plugins I use are listed here: 
https://github.com/henrik/dotfiles/tree/master/vim/bundle That repo has the 
rest of my vim config, too.

Wonder if it might be Syntastic - I've heard something about it being buggy, 
though not specifically about crashes. It runs on every save. Not sure what I 
was doing just when it crashed, I'm afraid.

Can you please report this problem to the vim_dev Google Group?  Include e.g. 
the latest crash log and link to this issue report, then ask if anybody can 
give any hints on how to track down the cause of this crash.  Oh, and also 
mention which patch level you are at (type :ver).

I had a look at your plugins and it is not really feasible for me to try them 
all out to try and track down this bug.

It would be helpful if you could compile MacVim without Ruby support (leave out 
the --enable-rubyinterp flag to configure) and see if that suffers from any 
problems.  (Of course this means you won't be able to use plugins that rely on 
the Ruby interface.)

I'll see about reporting the problem to them.

I just had another crash (" Vim: Caught deadly signal SEGV", don't see a full 
crash log), and I could tell from the restored swap file that I was probably 
autocompleting using the tab key. Tried the very same autocompletion after 
restoring, and I got the same crash again. But after restarting again I don't 
get it.

I'll try removing any customizations/plugins around tab completion and see if 
that helps.

OK.  Please try and keep reproducing the bug and let me know what was going on 
when it crashed -- I may be able to provide some insight.

Hmm.  That is a crash inside the PSMTabBarControl framework and has 
(presumably) nothing to do with the other issue.

This bug was introduced with Lion and occurs with the command line vim that 
comes with Lion.   What ever plugin/vim component is causing the crash is 
installed by default by Apple.

A friend said MacVim stopped crashing, possibly with OS X 10.7.2 or with 
MacVim. 7.3 (62).  I'm still on 7.3 (61) and I don't believe I've had crashes 
since OS X 10.7.2, and neither has my colleague. Should give it a few more 
days, but it might have been resolved.

OK, please let me know in a couple of days how it goes.  I still have no real 
idea as to what this problem is (since I've had zero crashes myself).

Hadn't had crashes since I wrote that comment, but had one today. Don't know if 
it's related to the earlier crashes. Things are definitely much, much better, 
either way.

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)

See attached log.

Every crash log (bar one) that you post have been crashes in core Vim.  I can 
only fix MacVim problems so please report this to the core Vim developers.  
That is, post to the vim_dev Google group.  Thanks.

I'm seeing a SEGV as well building with homebrew:
brew install macvim --HEAD

The problem appears to be happen with python plugins like VimRepress and 
UltraBlog.  That said I can do :python print 'hi' no problem.

Original comment by chnic...@gmail.com on 4 Nov 2011 at 4:24

Determined that running this command can reproduce the crash:
:python import sys; sys.stdout.write("Anything");

or 

:python import sys; sys.stderr.write("Anything");

Excellent! I can reproduce with the lines from comment 22.  I will try to debug 
this within the next couple of days.  Thank you.

Well, the Python issue is a 64 bit issue.  Adding "--with-macarchs=i386" as a 
flag to "configure" makes the problem go away (this flag causes MacVim to build 
as 32 bit, as opposed to 64 bit which is the Lion default).

Everybody who has stability issues should try compiling 32 bit and see if that 
fixes their issue.  I'll continue debugging to see if I can get a working 64 
bit version to compile.

Original comment by bjorn.winckler@gmail.com on 5 Nov 2011 at 11:38

GoogleCodeExporter commented 9 years ago 
Was finally able to get this working with homebrew:

1. brew edit macvim and set the 'arch' variable to i386 (line 33)
2. Ensure you are using the system ruby (I had a 1.9.2 x64 version set with rvm 
and that would not build with i386 set) if you use RVM just do "rvm system"
3. brew install macvim --HEAD

That did it.  Python plugins are working.  I did have to recompile command-T 
using the system ruby as well (there may be other plugins that need this too)..

GoogleCodeExporter commented 9 years ago 
Thanks for the confirmation.  I've asked on vim_dev if anybody has any ideas 
why Python and 64 bit don't match.  If anybody reading this has any ideas, 
please let me know.

I experienced trouble with MacVim (snapshot-64) installed with home brew.  In 
particular, all open windows would be closed upon:

1) running ":python print 2+2"
2) opening certain python file from my site-packages folder

My fix, after reading issue 370 and issue 392 was the following:

brew unlink python;
brew unlink macvim; 
brew install -v --force macvim; 
brew link macvim; 
brew link python

My problems have disappeared.  Also, it appears to be 64-bit.   E.g.:

:python import sys; print sys.maxint
> 9223372036854775807

Thanks,
- S.
