You're not using the latest gcc, which is 4.8.1-3. 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.preremove
Ah, 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.
