[SOLVED] Electron applications (discord, code) segfault on launch

I did a system upgrade yesterday and after that, VS Code (from aur/visual-studio-code-bin) has stopped working for me. It simply crashes on launch without any indication. I looked up and saw people getting it to work by changing cursors, but that did not fix it for me.

Here is the info from the coredump. (coredumpctl info <pid>)

https://pastebin.com/mLWjERRt

The same happens for Discord but that was the same even before the system upgrade. Before the upgrade, VS Code worked fine but not Discord. I am at my wit's end with this and don't know how to fix this.

Here is the dump for Discord: https://pastebin.com/z0eWAbfF

Any help in figuring this out would be greatly appreciated! Thank you for your time.

Re: [SOLVED] Electron applications (discord, code) segfault on launch

I checked various versions and noticed this issue started happening from v1.95.1. v1.94.2 works just fine. By the way, I am using X11.

Re: [SOLVED] Electron applications (discord, code) segfault on launch

Both crash in fontconfig parsing, do you have some custom fontconfig files?

Thanks for the quick reply. Yes, I do. Here it is:

By the way, how did you deduce it?

Re: [SOLVED] Electron applications (discord, code) segfault on launch

Advanced reading skills I picked up in elementary school

                Stack trace of thread 33247:
                #0  0x000057c25ccec413 n/a (/opt/visual-studio-code/code + 0x5ace413)

                #5  0x000072829c9b0fdd n/a (libfontconfig.so.1 + 0x2bfdd)

Remove the file to check whether it's actually the trigger.
If it is, wild guess, try to add a trailing newline.

Re: [SOLVED] Electron applications (discord, code) segfault on launch

I removed the fontconfig file and restarted my PC (just to be sure). But VS Code still crashes.

Here's the coredump: https://pastebin.com/NCACTY6J

The libfontconfig is still there in the trace.

Re: [SOLVED] Electron applications (discord, code) segfault on launch

strace -o /tmp/codeisastupidname.strace -tt -f code

/tmp/codeisastupidname.strace will then hopefully show what file it stumbles over…

The trace was pretty big this time. Here it is: https://files.catbox.moe/7l8tz4.strace

Re: [SOLVED] Electron applications (discord, code) segfault on launch

Okay, so I found a fix for VS Code at least. My XDG_DATA_DIRS did not include ~/.local/share/ and adding it fixed the issue for me. Discord still crashes though.

Re: [SOLVED] Electron applications (discord, code) segfault on launch

So you've two differently caused memory corruptions in electron processes that both by random chance go through fontconfig xml parsing??
Also

grep '\.local/share' kylkpx.strace | wc -l # 159 hits

Re: [SOLVED] Electron applications (discord, code) segfault on launch

After a restart, Discord started working just fine. I think the issue was with XDG_DATA_DIRS and adding the fix above makes everything work. Thanks!
