Christopher:
As I replied to Larry in a previous posting in this thread:
% ls -l /bin/cygwin1.dbg
-rwxrwxrwx 1 ingber None 9753672 Aug 2 20:50 /bin/cygwin1.dbg*
I followed your instructions: I downloaded the latest src from snapshots
and simply placed this file under /bin/. I got out of cygwin and got back
in again (several times) -- e.g., when "out" I mean there are no cygwin
processes under CNTL-ALD-F, etc.. Is there something else I should do?
Also in my .tcshrc file I have
setenv CYGWIN "error_start=c:/cygwin/bin/gdb.exe"
Clearly this must work to some extent as I am getting DOS-gdb popups
instead of crash files. Is there something else I should do?
Here is the output you requested:

Sorry. That is still a nonsensical back trace and it still seems as
though you don't have cygwin1.dbg installed. I still don't understand
why gdb is even in this state, either.
What does "info threads" show?
