A Hexen issue.

[AvzinElkein]

I was playing vanilla Hexen (the very first map) on GZDoom 3.7.2 when the thing suddenly crashed. Report is attached.

I just noticed your post.
You or the report do not mention which renderer you used. It is always good
practice to be as specific as possible when reporting such a bug. None of the
supporting programmers are mind readers. Mentioning where, when and how
the bug occurred in the map would be helpful.

Also, report it in the appropriate thread, see above on the page,
either Software Renderer Bugs or OpenGL Renderer Bugs.

The last piece of advice is only warranted if it can be confirmed that a bug only occurs with one renderer and not the others.

I disagree here. A lot of people are one-renderer type folks, and do not play the other renderers that are available.

So when "software" becomes "normal" for such people, they will omit that crucial bit of info because ... well, from their perspective - I'm not the only software renderer user, right? ... right?

True enough.
I just assumed that AvzinElkein would know which renderer the game was set to.

I meant putting bugs into the subfolders if they are not confirmed to be renderer specific.

I was using the Doom Software Renderer, actually.

Ok. So what happens is that the software renderer tries to render the null texture. The problem is, the null texture is not a valid texture and cannot be rendered.
This happened because the BLANK texture was not cleanly handled. Instead of making it a null texture it was animation-mapped to a null texture and some code in the software renderer did not account for that possibility. Changing its actual type directly fixes the crash.

This was some ancient hack from long before ZDoom had a texture manager and apparently the software renderer never properly handled this case, it was just happenstance that some recent change made it throw up on it.
