Fixed.

@Rachael : if it's okay you could apply the Git patch and add (patch by drfrag). I don't think doing a PR for this is worth but i could.

gzdoom.exe -iwad doom2.wad -file your_path_to_mock2\Mock2.wad

Code: C0000094 (Integer Divide By Zero)
Address: 00007FF7EB621480

Run GZDoom (fresh one) with mock2.wad.

Link to Mock2: [url]https://www.doomworld.com/idgames/levels/doom2/Ports/megawads/mock2[/url]
How I ran: [code]gzdoom.exe -iwad doom2.wad -file your_path_to_mock2\Mock2.wad[/code]

In menu set [b]Options->Set video mode->Doom Software Renderer[/b] (from Hardware accelerated).

Will crash on the spot when starting new game. It also will crash if you start game in Mock 2 using normal renderer, then change renderer to Doom Software Renderer. In this case it will crash when you restart level.

I have crash report, but I do not see any way to attach it here. Summary:

I do not know if any other wads are affected - I checked with doom2.wad and everything seems to work fine. I discovered it accidentally - 6th level in Mock 2 utterly destroy my computer for some reason (mere 720 cyberdemons and their rockets, pah). It is playable on software renderer, but then I've got killed and game crashed after restarting level...
