The Squid Cache (version 2.2.PRE2) died.

We've received the next message from squid:

>You've encountered a fatal error in the Squid Cache version 2.2.PRE2.

No core file was created. Only have found this message in th cache.log:
        
        FATAL: Received Segment Violation...dying.

Any idea on what's happening?
Thank you.
