Dear all,
FreeBSD RELENG_7.0 crashed when running super-smack benchmark test upon
jailed postgresql.

Previous frame inner to this frame (corrupt stack?)
(kgdb)
The super-smack is compiled from port benchmarks/super-smack with option
WITH_POSTGRESQL enabled.
The Postgresql is in a jail environment, packages are
postgresql-client-8.2.4
postgresql-server-8.2.4_1
The crash occurred only once, and I can not reproduce it after rebooting.
Best regards,
Chris Chou
