Just to save you from observing pinkt elephants: compile without optimizations
before you try gdb (i.e. with -O0, plus -g to get debug symbols).  Also, make
sure there is no -DNDEBUG when compiling (or provide -UNDEBUG to override it),
otherwise assert() will not fire and you will skip a lot of sanity checks.

Regards,
Jö.

If you receive something that says "Send this to everyone you know,"
pretend you don't know me.
