[squid-users] squid 3 crash

Hey all,

I've been playing with/learning squid 3 and I've been able to
consistently crash squid simply by fetching a static html page. I'm
wondering if this is a well-know problem in squid 3, or if I'm just
doing something wrong/weird.

Any help would be appreciated.

Here's my setup:

Squid 3 on an AMD 64 bit processor.
Squid's set up as an http accelerator for virtual hosts.
Only one cache peer exists in the config (localhost is running apache
on port 81):

cache_peer localhost parent 81 7 no-query no-digest no-netdb-exchange
connect-timeout=5 originserver

Here's what I've done:

- Start squid fresh (w/ empty disk cache).
- Load a static page (with one image in the HTML) in firefox from a web server
- Kill squid (SIGTERM)
- Start squid again
- Load the same static page (by clicking "refresh" in my firefox window)

When I try to load the static page again, squid dies.

This is the stack trace from gdb:
