Sigh. I was under the impression that someone had fixed this.

Of course, this has nothing to do with insight. I would harrass the
dejagnu maintainer about the problems. :-)

Make sure that you don't build Insight with optimization and run it
under gdb. When the error occurs, gdb will stop the process immediately.
You should have a valid, readable stack backtrace (unless it was
corrupted, of course). Use the distributed gdb to run the "bad" one.

BTW, can you describe what you're doing to crash it? (aka: test case).
Although I have not extensively tested on cygwin in a while, I do some
basic sanity checking, debugging insight with insight.

There is no difference of which I am aware. I think it's just
nomenclature.

I guess I'm just lucky? I still cannot reproduce any of these cygwin
errors (the Win98 and dejagnu problems excepted). Argh. I think this is
at least as frustrating for me as it is for everyone else. :v(

PS. If you're using CVS snapshots/CVS HEAD: make sure you get my patch
to src/Makefile.in. There was a small configury error which I never saw
because I had installed versions of insight (and tcl, tk, itcl, etc)
available. When configuring the gdb directory, make sure that "looking
for private itcl headers"-like stuff comes from the src directory and
not some random package on the system.
