Integer divided by zero fatal crash on GZDoom v14.2.2 Windows 11

[Goldberg]

I don't have any knowledge on Doom mapping, so here we go:
Received fatal crashes for GZDoom v14.12.2, tested on four wads (myhouse.pk3, PB-0_1_0-alpha.pk3, brutalv22test3.pk3, RO.pk3), Ashes doesn't count probably since i use the standalone version
Code: C0000094 (Integer Divide By Zero)
Report Log: https://www.dropbox.com/scl/fi/rjpbrhru ... blz8h&dl=0
There was one report in the forum for 4.11.something but there has been no updates for a while, no previous reports found

Somewhat detailed description:
1. myhouse.pk3, crash when attempting to noclip and teleporting to backrooms and also when going upstairs in the burning house
2. PB-0_1_0-alpha.pk3, menu works fine, but attempting to start the game gives you a brief black screen following the melt effect, then the game crashes
3. brutalv22test3.pk3, instant crash when trying to run through GZDoom
4. RO.pk3, crash when starting map
Tested 2 and 3 on LZDoom, obviously 2 does not work as the mod author said, however, 3 and 4 works.

My PC Specs (more like.. laptop):
CPU: Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz 1.80 GHz
RAM: 4,00 GB
System Type: 64-bit operating system, x64-based processor
GPU: Intel UHD 620 and AMD Radeon 530 (both has no different effect on crash it seems, and both have no vulkan support)
OS: Windows 11 Home Edition

GZDoom settings:
General: Fullscreen
Rendering API: OpenGL
Extra Graphics: Widescreen

It's good to know that I haven't had this crash before on this device on version v4.10.0

Does this crash still occur in the Vulkan renderer? The OpenGL one is effectively deprecated at this point and should generally not be used outside of testing. That chipset supports Vulkan. Vulkan and OpenGL-ES backends are favored.

Also you might try to see if those mods will run on VkDoom - you might have better luck with that since it has undergone some major rendering revamps.

I'm pretty sure the UHD 620 has Vulkan support -- see here: https://vulkan.gpuinfo.org/listreports. ... aphics+620.

Ah, my bad then. Turns out both do indeed have vulkan support, but I must have mistaken it for a completely different game's mod. No crashes using vulkan now, thanks!
