Description of problem: 1) Use a simple fontfore script where it will open the sfd file e.g. say generate.ff fontforge.open() 2) get any sfd file e.g. FreeSans.sfd from gnu-free-fonts upstream tarball 3) run following command /usr/bin/fontfore -lang=py -script generate.ff FreeSans.sfd This will cause core dump.
