crash with soundless mound

Post by drfrag »

I've found a crash in software mode with soundless mound (soundless_m.pk7). viewtopic.php?f=19&t=60219
In hardware GL mode i get an assert failure instead, gl_walls_draw.cpp:53, assert(wall->vertcount > 0);
I think it's the same problem. Warp to x=7500,y=9500 (that room) and turn around to reproduce.
This is a crash log for the vintage build, modern also crashes.

Going to see if I can get more details for this on my end, this might be some hidden bug that only popped up because of the specific fog setup I used in that spot.

Edit: From what I got, there's something wrong with drawing line 9174. That's weird, it's just an invisible two-sided line.

PS: I cannot reproduce the crash on OpenGL.

It won't crash in hardware mode, just gives an assertion failure with debug builds.

I'm doing debug builds but I get no such assert, maybe it's just a Windows thing.

Or may be the assertion only appears in the vintage build then... I get it with both VS and MinGW.

Since the crash only happens in software mode (Carmack renderer only) now i think it's better to move this to Software Renderer Bugs.

Okay, so I don't know what's going on here, but this does not crash on the modern branch. I tried to copy the swrenderer folder in full to the Legacy branch but that does not appear to fix it. The variable that's buggering up is "MaskedSWall", my guess is, it's a thread data that's deallocating before its thread gets executed. Or perhaps it has something to do with being 32-bit vs 64-bit.

Last time i checked it still crashed in the modern version, it's the same renderer and even crashes in LZDoom.
I've just checked again with the latest devbuild and still crashes as expected, this is a 32 bit build.
Fun fact: this is an old GL 3.3 ati card and now i only get a blob with colored dots, i expected it to run at least in software mode. I've blindly warped to that location and looked around to reproduce the crash.

Edit: i thought this was intentional but now i've made a bug report. Just tested soundless mound with gzdoom-g3.6pre-57-g2d1043d1d.7z (that one runs properly here) and soundless mound still crashes.

I've tried the latest x64 vintage devbuild on my laptop and it doesn't crash so it's a 32 bit only thing at least with VS. Earlier i tried the modern 32 bit one and it crashed.
