I just started using DJGPP with RHIDE and experienced the same thing, certain
expressions in the debugger cause RHIDE to exit and leave you back at the DOS
prompt (in my case, a DOS box running under Windows/NT).

If you look in section 5.3.2 of the RHIDE documentation for version 1.4 you find
the following:

"A known limitation is, that the expressions are NOT checked for validity. That
means, you can produce any exception there, which will terminate your program.
As
an example type in the expression input line

3/0"

I assume that is the cause of our problem.  It doesn't look you can do much
other than work around it.

Generally, though, I have been very impressed with RHIDE.  It has been fairly
robust for the other simple things I have tried.  I have also taken a look at
RSXNTDJ but it seems to require a fair amount of patching to make it work and
when I ran it I couldn't figure out how to make the editor work.  The only
choice I recognized was WinWord and when I selected it it wouldn't run (perhaps
because my German is non-existent and I can't figure out the option boxes).  I
haven't seen any posts from the original author so I think he has moved on to
other things.  My thought is that it would be better to wait for CygWin32 to
stabilize and try using that once I feel ready to tackle Windows.

I use Microsoft Visual C++ at work and find the whole Windows paradigm (sorry, I
know it's an overworked word) to be far more complicated than necessary.  I
suspect it's a case of Microsoft rushing to build the Windows platform and then
it's been one rewrite after another - no different from any of the other
software companies I've worked at in the last 20 years.
