>> Its not difficult, but takes some time.  The error happens when make compiles one lisp file at the time with emacs.  It appears to be random so it does not crash in the same lisp-file.  Thus, you have to start emacs from gdb, and repet run, quit in gdb for each lisp file until it crashes.  Running in gdb is slow with cygwin, and running in gdb makes the bug appear less often.
