HEAPCHECK=normal gets stuck on ArchLinux #396

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have a small ArchLinux setup with the newest Kernel/compiler/perftool 
version. Tcmalloc works fine as it boosts my performance significantly! But 
HEAPCHECK does not work.

What steps will reproduce the problem?
1. Install basic ArchLinux system
2. compile any code with whatever gcc version linked with newest tcmalloc
3. env HEAPCHECK=normal ./test

What is the expected output? What do you see instead?
Expected: At least any output from perftools
Observed: The program gets stuck without any load! This issue is independent 
off the actual program. So following example will also not work:
int main(){
    return 0;
}

What version of the product are you using? On what operating system?
svn revision 132
libunwind-0.99 (I've read that there are problems with newer versions)
#uname -r
2.6.32-LTS or 3.1.9-2-ARCH

Please provide any additional information below.

With the same tcmalloc and libunwind version everything works fine on a 
Scientific Linux system (2.6.32). Independent on which machine I've compiled my 
test code.

How can I debug this? Strace doesn't help as I get following output (which 
confirms that tcmalloc ist at least doing something):
strace env HEAPCHECK=normal ./test

...
close(3)                                = 0
write(2, "Someone is ptrace()ing us; will "..., 48Someone is ptrace()ing us; 
will turn itself off
) = 48
write(2, "Turning perftools heap leak chec"..., 41Turning perftools heap leak 
checking off
) = 41
...

What are the libraries that I can compare between my working SL and my broken 
Arch PCs to find some differences that probably lead to my problem?

Update:
Actually I meant svn revision 133

I'm running on a x86_64:

And that's it. No more output and no return of the program.

[I'm sorry for the late response.  When I renamed the project to gperftools I 
forgot to re-enable email alerts, so I haven't been getting bug reports.  I 
just happened to notice now.]

You can debug this in gdb.  You'll need to do something like
   env HEAP_CHECK_RUN_UNDER_GDB=1 HEAPCHECK=normal gdb ./test

then type 'run'.  If it hangs, you can do control-C and 'bt' to see where it's 
hanging.  Hopefully that will give some clue.

You don't mention, but are you using libunwind?  Try running configure with 
--enable-frame-pointers to see if that makes the problem go away.

Thanks for your answer!

So at first I'm using libunwind-0.99 as I mentioned above. Is there a newer 
version that works with tcmalloc? I remember that I had problems with the 
newest version a few months ago...

I just configured perftools with --enable-frame-pointers and reinstalled but 
nothing changed with small test programs. With my real program I get a lot of 
errors (looks like some 32-bit windows files are included that mismatch with 
the rest)

On the other hand your gdb proposal helped much more. The full reproducable 
shell code:

# echo "int main(){return 0;}" > test.c
# gcc -ltcmalloc -otest test.c
# ./test
# # So here everything works fine. The program returns immediately
# env HEAPCHECK=normal ./test
^C
# # Here I had to ctr+c as the program got stuck
#
# env HEAP_CHECK_RUN_UNDER_GDB=1 HEAPCHECK=normal gdb ./test

I solved this by backporting the following glibc commit
20b38e0301279a37a3f1e769843933bcc0d5f736
to Arch's glibc package (glibc-2.15-4), and recompiling google-perftools with 
it.

Apparently sscanf always calls malloc instead of alloca which triggers some 
deadlock. Here's the mailing list thread:
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/17093

Good luck.

Thank you very much for this post! Sounds like this is the problem, but I'm

Well I hope that I will find some more time to investigate on this or probably 
a glibc 2.16 release with this issue fixed is faster than me ;-)

Glad to hear that the problem was diagnosed.  It doesn't sound like a perftools 
issue, so I'm closing the bug.  (Feel free to reopen if I'm mistaken.)
