PlugData crashes on arch linux

[FlachyJoe]

I'm running Xubuntu 21.10 x86_64

[timothyschoen]

Should be fine with pipewire. The problem here is caused by a failure to load the keyboard shortcut preferences, thanks for letting me know! I'll have it fixed very soon!

[aik2mlj]

Also the standalone version can't run as well..

./Plugins/Standalone/PlugData
fish: Job 1, './PlugData' terminated by signal SIGSEGV (Address boundary error)

[FlachyJoe]

I confirm the standalone issue

Thread 1 "PlugData" received signal SIGSEGV, Segmentation fault.

Thanks for reporting, I'll check it out. I wrote that function pretty recently, so I guess I made a mistake somewhere! Are you both on Arch btw?

[timothyschoen]

Fixed it!

Small warning: there have been huge improvements since the last release, and I'm still working to ensure everything's stable. A known issue is that the width of certain objects can sometimes change incorrectly, and there might still be more issues. If you find any, please report them, it helps a lot!

Well I'm still experiencing segmentation fault after pulling the newest commits.. Here's the backtrace info

btw I'm using pipewire. Is it related?

[aik2mlj]

Cool! Also do you mind me adding PlugData to AUR? Would be much more convenient for other arch users in that way :-p

[timothyschoen]

I'd like to do that, the only problem is, I've never used arch (I know, embarrassing), so I'll have to read up on it first. And before I do that, I'd like to make sure that crashes like these don't happen anymore!

The bug should be fixed now, let me know if it works or if you have any more problems!

[aik2mlj]

Yeah it launched! Thanks for your effort! I mean I can help add PlugData (git version) to AUR if you like ;)

[timothyschoen]

I would really appreciate that! You could do it with the current version if you want to, but I expect to fix a lot of issues in the coming weekend, so you could also wait until Monday. I'll leave that up to you :)
