My first suggestion - to you and others that have been requesting
help with vaguely similar issues - would be, give up on RHIDE.  It's
not been supported (for DJGPP, at any rate) for years now - which
means that there are a host of problems with using it with the modern
toolchains (and often with modern machines as well).  For instance,
under GCC 3.x or greater, you cannot put breakpoints in C++
constructors or destructors; they will simply be ignored.  You often
cannot inspect member variables.  Breakpoints often crash or give
unpredictable results... etc., etc.  (And yes, that's even with
optimization disabled.)

My suggestion would be to use "gdb -tui" instead; the latest GDB
download supports the TUI mode.  This still requires that you learn
the GDB command-line, but it's not as bad as one might think.  And
as you get more used to it, you'll discover that you can do things
with it that you could never do with RHIDE.

It'd be nice to get RHIDE/RHGDB fixed, or get another frontend...
but until then I don't think it's worthwhile to try and fight with
it.
