Quake was compiled with an early beta of DJGPP v2.0 and it is run
using an early version of CWSDPMI, both of them dating back to 1995.

standard crash message and traceback?

If so, please run the SYMIFY utility on the traceback and post it

What version of CWSDPMI do you have installed, btw?  (Assuming you use
CWSDPMI as your DPMI server; if not, please tell what do you use for

Did you see these problems in any other programs except these two?
Can you try to reproduce them with one of the utilities shipped with
