The biggest problem I've had is a propensity for gcc to crash on systems which use HIMEM.SYS
but not EMM386 or Windows.  The symptoms, which occur on about 1% of the compilations, are a
bomb in an RMCB with a traceback.  The keyboard then invariably locks up, necessitating a hard
re-boot, though the disk cache continues to commit normally after the lock-up.  I have
observed this problem on several computers.  Oddly enough, my own DJGPP-compiled apps have
never had this problem.

I don't know for a fact that CWSDPMI is involved in this, but since EMM386 (or Windows) seems
to prevent these lock-ups makes me suspect that CWSDPMI is involved.

Since I have no reason to use EMM386 (other than to prevent this problem), and since EMM386
interferes with other things on my system, it would be nice not to have to use EMM386.

I don't know what I can do to diagnose the problem, other than to manually transcribe the
traceback.

This is an old problem I've lived with for a couple of years, which I have reported before,
but it hasn't gone away.
