Then I guess we will have to debug it in the optimized build. But before you get back to that, could you try a slightly different configuration: CFLAGS='-Og -g3' ./configure --enable-checking='yes,glyphs' ... (If -Og doesn't work with your GCC, try -O1 instead.) If this build doesn't reproduce the crash, just rebuild with full optimizations. > Since it's compiled without optimizations now, is this a bug in GCC > itself?

OK. So I'd like to see the output of those 2 GDB command in a build that does crash. Thanks.
