Crash while attempting to load KDIZD in software renderer

GZDoom crashed immediately upon attempting to load KDIZD in the software renderer. This seems to a few other big mods with custom maps (such as Doom Lost Alpha) in the software renderer, although they crash once you start a game (unless they have a titlemap like KDIZD). It's possible to avoid the crash by starting in OpenGL and then switching to software after a map has loaded. Speaking of that, there's another issue which I'll get to in another thread.

EDIT: This is with 3.7.2.

EDIT 2: It also happens with true color software, softpoly, and true color softpoly.
