signal 11 in gzdoom (on a specific level)

[missingno3567]

Hello!
I was playing some Guncaster 3.3 (with addons) on the Doom 2 version of mapsofchaos-ok when on map12 it suddenly crashes for no reason when i cross certain sections of the map. It's replicable but it only ever happens if i load Guncaster (with or without addons) and mapsofchaos-ok. If i just load the wads individually or use another edition of mapsofchaos, it doesn't happen. I'm using gzdoom alpha (from git and compiled following the instructions on the wiki), compiled on clear linux by me, but it also happens if i try it with the downloaded sourcecode from the site. I'd test it with a precompiled version but my linux doesnt allow that (i could use a flatpack or appimage, but that's it). I read up on it a bit and from what i've gathered it has something to do with the GL drivers, but switching to doom software gave me the same results. (In case it matters, i got a cheap laptop with intel integrated graphics and a radeon gpu, if it's important i could send more info).

The terminal output is:

I'd appreciate help, even if its just a way to find the issue (i also have a problem with archviles targeting me through walls, probably an issue with the build but idk how to fix it).

This can be a bug in engine. It will help if you explain in detail how to reproduce the crash. Also, you can provide a saved game right before the crash.
