I also experience this issue lately.

I also can't give a way to reproduce this error, seems very random to me.

The applets I use are IcingTaskManager and Weather.

[mcarans]

I am also using Icing Task Manager, but even when I disabled it for a while, I still got the crash, so don't think it is related to that applet.

[mcarans]

Author of Icing Task Manager confirmed it is not in Icing causing the crash and referred to this upstream issue: GJS crash in needsPostBarrier, possible access from wrong thread

[leigh123linux]

https://github.com/linuxmint/cjs/pull/49

[leigh123linux]

@mcarans without a full backtrace (complete with cjs debug symbols) this issue is unlikely to be traced and fixed.

[mcarans]

How do I produce a backtrace?

[leigh123linux]

Try https://github.com/linuxmint/Cinnamon/wiki/How-to-use-GDB-to-gather-debug-information-on-a-program

[leigh123linux]

@mtwebster Can you guide them on how to produce a useful backtrace as this process is automatic in fedora :-)

[mcarans]

The link above talks about using another computer to ssh. Is there any simple way to get a backtrace that doesn't involve using another computer?

Also this crash did not occur with Mint 18.1 and earlier, so can I downgrade CJS to see if that helps or will that cause other problems?

[itzexor]

You can use this script[0] to dump a backtrace when cinnamon crashes without needing a second computer. Run it as ./cin-debug cinnamon and it will prompt you for password because root privs are required to attach the debugger to a running process. After cinnamon crashes there will be a log in your home directory with the backtrace.

[0] https://raw.githubusercontent.com/linuxmint/Cinnamon/master/utils/cin-debug

Note: the libcjs-dbg package was only recently added to cjs for dpkg-based distros, so I'm not sure that debug symbols are currently available in Mint. You may need to build cjs manually to get them. Without debug symbols the produced backtrace will be unusable.

[mcarans]

I am not sure if this gives what you need:

@clem could you tag cjs please?

[mcarans]

Does 3.4-maintenance branch have that fix (as that branch as of 6 days ago is what I have installed currently)?

[tetious]

I'm seeing this crash too, with cjs/libcjs 3.4.4 which should have the mentioned fix. So I don't think it is fixed.

cinnamon[2181]: segfault at 7fba62dfffe8 ip 00007fbac7c22555 sp 00007ffd826ba140 error 4 in libcjs.so.0.0.0[7fbac7bf9000+c2000]

[mtwebster]

@tetious can you provide the output of the following (just a couple of sanity checks):

cd /
find . -name "libcjs*" 2>/dev/null

and (assuming you're on mint or debian-based - I want to make sure only the correct versions are there)

dpkg --list | grep cjs

Thanks

[tetious]

[mcarans]

I had the libcjs crash again this morning running 3.4.4+sonya. I will try to capture the stacktrace with the script @itzexor provided the next time it happens.

Here is the stacktrace:

I guess the ?? means there aren't debug symbols - if you need them, please tell me the steps to compile a debug version of what you need.

@mcarans The backtrace is complete enough.

@mtwebster Is it possible to provide some cjs deb packages including the fix from https://bugzilla.gnome.org/show_bug.cgi?id=785657#c7 for testing.

[naith]

I have this same trouble. Cinnamon crashes with SIGSEGV today in twice. Mint 18.2.

removed useless backtrace

[mtwebster]

Please try these - download all of them first, then run, from the directory they're in,

sudo dpkg -i *cjs*.deb

(make sure these are the only cjs packages in that folder also)

https://dl.dropboxusercontent.com/u/8201170/libcjs-dev_3.4.3_amd64.deb https://dl.dropboxusercontent.com/u/8201170/libcjs-dbg_3.4.3_amd64.deb https://dl.dropboxusercontent.com/u/8201170/libcjs0f_3.4.3_amd64.deb https://dl.dropboxusercontent.com/u/8201170/cjs_3.4.3_amd64.deb

If anyone needs them I'll do some 32-bit ones also.

[mtwebster]

Anyone who hasn't yet, please report what graphics hardware and driver you're on

[SethosII]

For me it is VMware:

I have started cin_debug and will give you a trace next time it happens.

[mtwebster]

Can you tell us what applets, desklets and extensions you’re running? Try disabling and making a note of any 3rd party ones (ones you may have downloaded, that weren’t pre-installed), particularly system monitor or hardware monitor types.

[tetious]

For me, the crashes were happening at least once a session until I disabled Icing Task Manager. After disabling it, there has not been a crash since.

[mcarans]

Interesting, I have only one: Icing Task Manager. With previous versions of libcjs, I had tried disabling Icing but still got the crashes. I can try again. @jaszhix making you aware of this development.

[buggyRogers]

I'm using the applet 'Network Data Usage Monitor'. I downgraded to cjs Version 3.4.2 on a Manjaro Cinnamon Desktop Version 3.4.4 with Nvidia driver and have no crashes since yesterday morning. I can try to update to cjs 3.4.3 again and disable Network Monitor.

[jaszhix]

Sorry, I don't see how I can help improve the situation, I don't see any information in the logs pasted here relating to ITM. If you come across a JS error, that would be a starting point for improvement, but otherwise it still seems like a bug on the interpreter side. Also, pull requests are welcome.

[mcarans]

@buggyRogers How did you install cjs 3.4.2?

[buggyRogers]

@mcarans I run Manjaro and had it in the package cache. I installed it with: sudo pacman -U /var/cache/pacman/pkg/cjs-3.4.2-1-x86_64.pkg.tar.xz

If you don't have it, you can get it from the archive: https://archive.archlinux.org/packages/c/cjs/ Trying now 3.4.3 without Network Monitor applet.

[mcarans]

@buggyRogers thanks. Unfortunately that won't work for me - I am on Linux Mint.

[SethosII]

@mcarans see here: https://askubuntu.com/questions/138284/how-to-downgrade-a-package-via-apt-get#138327

[mcarans]

I tried apt-cache showpkg cjs but unfortunately there is only 2.8.0-1 available before 3.4.3.

I have built 3.4.2 from source from release here: https://github.com/linuxmint/cjs/releases and will see if it crashes. It replaced all the cjs packages except: libcjs-dbg which is still the patched 3.4.3 (https://dl.dropboxusercontent.com/u/8201170/libcjs-dbg_3.4.3_amd64.deb).

[mcarans]

3.4.2 crashes for me. Now trying 3.4.4+sonya without icing or any other 3rd party things.

[mcarans]

3.4.4+sonya with no icing has not crashed for me since I last posted. Perhaps it is not a bug in icing itself but a bug that icing reveals in libcjs by calling something that is not called by the base Cinnamon installation.

@jaszhix running check-js against IcingTaskManager@json/3.2 returns

Line 128 contains:

_addFavorite: function (opts={appId: null, app: null, pos: -1}) {

Default parameters are valid in mozjs38 (and this particular way should be in mozjs24). Does the check-js script account for those?

[buggyRogers]

After disabling the panel applet 'Network Data Usage Monitor (netusagemonitor@pdcurtis)' it stops crashing. But I'm not 100% sure, maybe I was just lucky. :) I ran the check-js-script and the result was:

Checking for duplicate 'let' declarations - mozjs38 crashes if one is encountered within the same scope...
... no problems found

Checking for missing comma separators between prototype methods - cinnamon crashes if one is missed...
Missing comma after prototype method - './applet.js' at line 970
Missing comma after prototype method - './applet.js' at line 1143

The code in the mentioned line 970 is:

    on_applet_removed_from_panel: function () {
        // Prepare to stop the update timer
        this.applet_running = false;
        this.settings.finalize();
    }
};  <-- 970

If I insert a comma after the curly brace in line 970 the check is successful in this line. But now i can not add it to the panel.

glass.log shows:

error t=2017-08-21T19:24:58.351Z expected expression, got ';'

So it looks like the syntax is not correct. In line 1143 is the end of a comment section, last method over comment section is the main method.

Maybe it helps you ...

[mcarans]

The error "Missing comma after prototype method" outputted by check-js seems to be common to both the code of Icing and Network Data Usage Monitor - is this the cause of the crashes?

[jaszhix]

No, Network Data Usage Monitor doesn't use default parameters. The check-js script was made to help migrate the Cinnamon JS to mozjs38, but it doesn't account for all the possible syntax that's now available in ES2015 on mozjs38 and shouldn't really be used as a metric here.

I have been investigating very hard to reproduce orphan St. Label warnings that have been mostly addressed but still crop up occasionally. One day I saw a handful, and the last couple days I haven't seen any. That's the only issue in ITM I've noticed that could possibly cause an issue with the C bindings.

@mcarans I also remember you use the text labels for buttons - I would be interested to see if the crashes still occur when you disable those in the ITM config.

[mcarans]

Ok @jaszhix I will try: Title Display "None" today

[mcarans]

@jaszhix Unfortunately I have already had a crash with Title Display: None

[jaszhix]

Ah okay, thanks for testing.

If you see any St.Label orphan errors in .xsession-errors, please let me know.
