Thanks for the info. I should have mentioned that this is
OpenBSD/amd64, and I'm using the following malloc.conf options:
# ls -l /etc/malloc.conf
lrwxr-xr-x  1 root  wheel  2 Jun 24 17:18 /etc/malloc.conf -> AS

Although it coredumps without the malloc.conf also.

You can get a gzip'd coredump at http://ddp.devio.us/stratcond.core.gz

Thanks again!
