It's not clear what code caused the segfault, and in an optimized build one cannot trust line numbers reported by the debugger in a backtrace. You may need to disassemble the code in GDB to see what source line crashed. Also, please go to frame #1 (assuming that crashed session still exists), and type "p *it.glyph_row", then post here what GDB prints.
