This is expected if cpp and gcc are aborted by Windows.

So the problem only happens when cpp is invoked from GCC, or from
another DJGPP program...  Hmmm...

Please try the same invocation of cpp, but this time from go32-v2.
That is, prepend "go32-v2" to the above command line when you type it
at the prompt.  Does this work or does it crash?

Yes, this is how the preprocessor should work.

Btw, did you edit your djgpp.env file in any way?  Also, what version
of the specs file (in the DJGPP's lib subdirectory) are you using--the
one from djdev202.zip or the one from gcc295b.zip?
