Interesting.
First try this:
cd \tools\djgpp\bin
stubedit cc1.exe
Minimum amount of stack space? <enter some very large number, like 4M>

If, after doing that, GCC still crashes when compiling, would you please try
to reduce the source to the minimum compilable piece that reproduces these
problems, and send it to me (NOT the group). Also send me what compiler
flags you used, compiler version, whether it's the stock version or one you
built, etc. I will try to reproduce it. It's possible this is due to some
strange software config issue, or perhaps hardware failure (like bad RAM),
or it could be an actual GCC bug.

I think they would. If you transcribed it to text, that would be fine.
Compiling with the `-v' and `-Q' flags might help diagnose the problem, too.
