There is some strange memory corruption happening. I've not been able
to identify the cause of it yet, I haven't found a way to reproduce
the bug deterministically.
Sounds like fun. I presume that Valgrind isn't of much use here?
In any case, I think I made it clear, but fixing the free-under-GC I
reported doesn't resolve this.
