assertion failures

[Archie Cobbs]

I'm getting assertion failures in kaffe-snap Mon Jul 27 08:02:00 1998.
This is on FreeBSD.

My particular application is trying to use threads, which seems to
trigger the problem.

This is not deterministic. Sometimes I get the one at ./mem/gc-mem.c line 264:

How can I help debug this? :-)
