I get a 100% cpu use problem, but the gdb bt points to the GC, and
I've been informed that it is due to the use of references overwriting
finalizers (or something to that effect -- I don't fully understand
why it would crash/lock up and can't produce a testcase) (gcc bug
18266).
Maybe you can run it under gdb and look at the bt once it is locked
up.
