The best plan of attack is to try to make the bug reproducible, and with
as little runtime before the crash as possible.  Try to eliminate any
non-deterministic effects in your program (eg. the use of random
temporary filenames is one source of non-determinism that is easy to
overlook).

It's hard to say what the problem is at this stage, but it looks to be
GC-related.  Get to a reproducible point, then ship us the code and I'll
look into it.

Cheers,
