It would also not be very useful, since any info we could put into
such an error message could be quickly discovered by a little
investigation with a debugger.

I have to disgree with that, it's the instant gut ueber-programmer
reaction to such problems.   Currently the user just gets an exiting
emacs, leaving me with no clue as to why emacs exited.  I then have to
provide instructions to the user as to how to run the $*&$%#!!! debugger
to help me figure out what happened.  The debugger that he may or may
not have installed, and may or may not even be ABLE to install.

A simple last-ditch printf that says "corruption detected during
garbage collection, see you later" would be a much easier way to get an
initial handle on what the heck the problem is.  As it was, without any
message, my initial suspicion was a SEGV or similar, which would be
much more likely to be a Cygwin problem than an emacs problem.
