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 $ cd emacs-24.3 $ autoreconf -I m4 $ ./configure CFLAGS='-g -0g -fsanitize=address' LDFLAGS='-fsanitize=address' --without-all checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking build system type... x86_64-unknown-cygwin checking host system type... x86_64-unknown-cygwin configure: error: Emacs hasn't been ported to `x86_64-unknown-cygwin' systems. Check `etc/MACHINES' for recognized configuration names. In particular, it doesn't look like the patch actually patches any emacs files at all... do I need to pull all past versions of the source package as well or something?The source package for emacs-24.3-5 contains lots of patches that you didn't apply: nox_mouse.patch w32_encoding.patch configure.ac.patch syms_of_cygw32.patch image_background.patch w32term.w32_init.patch unexcw.patch memory_warnings.patch 24.3-4_nt_icon.patch nonbootstrap_static_heap.patch 24.3_memalign.patchI see... that would explain it. For future reference, though, how does one go about discovering which patches to apply? Most of those file names don't associate them with emacs in any obvious way, and `cygcheck -f' claims that none of them belong to any package... do you have to go dig up the source package's package file and look inside?
Take a look at emacs.cygport. It shows you exactly how the package was built, including patches.
