[squid-users] Squid 2.5.7 crashing

Today, squid started exiting/crashing with this message on stdout:

squid: util.c:612: xstrndup: Assertion `n' failed.

and was restarted immediately afterwards, since I'm running it under
daemontools' supervise.

This is squid 2.5.7-5 from Debian/testing.

These crashes repeated in rapid succession, several times (my scripts send
mail on each restart):

I then stopped squid, nuked the cache directories and restarted squid after
that. It seems to work fine now.
