Crash when moving in c3m1_b

[x3003]

In c3m1_b, when standing here and moving left/right I get an execution error:

"Execution could not continue.
Out of vertex memory. Tried to allocate more than 1999503 vertices for a single frame"

If I run towards the ladder and climb, there's no error. I can finish the level w/o further probs.

Confirmed. Bug is present in the latest gzdoom build and 4.12.2. Does this in both Vulkan and OpenGL, but not with OpenGL_ES or in BOA 3.1. It has its own issue in this area, which I'll report on separately. Might have something to do with the falling debris ?

Just to add, if anybody else tests this, the effect is not immediate, just keep on looking left and right and the game will crash.
