Ahah. I pressed C-c C-c to send this mail and it crashed. I just had to
be patient.

Attached is the backtrace. I've both the binary and the core file is
needed, I can provide them to you privately.

Configure was:
./configure --build x86_64-linux-gnu --host x86_64-linux-gnu --prefix=/usr --sharedstatedir=/var/lib --libexe      cdir=/usr/lib --localstatedir=/var --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --enable-loca      llisppath=/etc/emacs-snapshot:/etc/emacs:/usr/local/share/emacs/24.1.50/site-lisp:/usr/local/share/emacs/site-lis      p:/usr/share/emacs/24.1.50/site-lisp:/usr/share/emacs/site-lisp --without-compress-info --with-crt-dir=/usr/lib/x      86_64-linux-gnu/ --with-x=yes --with-x-toolkit=gtk3 --with-imagemagick=yes 

Make was called with:
make -j2 CFLAGS="-DDEBIAN -DSITELOAD_PURESIZE_EXTRA=5000 -g3 -O0"
