Check out the file how-to-debug-cygwin.txt in the CVS repository.

You can read this via the web via this link:

http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/winsup/cygwin/?cvsroot=src

You can use the techniques listed in this message to debug cygwin.

I can't offer any insight about what is going on.
