Also, there is a message which was printed in the terminal but did not get dumped into the file despite the &> redirection; that message reads simply "Segmentation fault".
Enable core dumping (ulimit -c unlimited) and make it crash again. Then load that core file under gdb (gdb core) and get the backtrace (bt). Attach it here.
