Any chance that that's your problem?Heh. I actually do have the latest gcc, but somehow the upgrade didn't pick up the debug package (which showed as not installed in setup.exe). I have manually upgraded it now.OK. But doesn't the above show that the crash is occurring in gcc, not emacs?BTW, how do you compile emacs from the sources given? I tried untarring and patching, but I get the message:configure: error: Emacs hasn't been ported to `x86_64-unknown-cygwin' systems. Check `etc/MACHINES' for recognized configuration names.One of the patches changes configure.ac, so you have to run autoreconf after applying it.Or it might be 'autoreconf -I m4'.Something is still wrong: $ cd /scratch $ tar xaf /usr/src/emacs-24.3.tar.xz $ patch -p1 </usr/src/emacs-24.3-5.cygwin.patch patching file emacs-24.3/CYGWIN-PATCHES/emacs-X11.postinstall patching file emacs-24.3/CYGWIN-PATCHES/emacs-X11.preremove patching file emacs-24.3/CYGWIN-PATCHES/emacs-w32.postinstall patching file emacs-24.3/CYGWIN-PATCHES/emacs-w32.preremove patching file emacs-24.3/CYGWIN-PATCHES/emacs.postinstall patching file emacs-24.3/CYGWIN-PATCHES/emacs.preremoveAh, it seems there's a /usr/src/configure.ac.patch that happens to belong to emacs... ... but unfortunately it seems that -fsanitize is only supported on Linux and Darwin right now, so there's little reason to build emacs unless you could use some particular information that a debug build provides. Rats.
But a build without optimization would make your backtraces more useful. Ken -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
