When I start gdb, I see the following: $ gdb /usr/bin/emacs-X11.exe emacs-X11.exe.core GNU gdb (GDB) 7.6.50.20130728-cvs (cygwin-special) [... copyright blurb ...] Reading symbols from /usr/bin/emacs-X11.exe...Reading symbols from /usr/lib/debug/usr/bin/emacs-X11.exe.dbg...done. done. warning: core file may not match specified executable file.
