[squid-users] Crash on Squid when clearign cache

Hi,
We are having squid crash a few times and creating Watson dumps when
user clears cache. We do stop the squid ( using Terminate Process),
clean the cache and restart it. This happens on field and we don't have
much info. The crash however seems to point to the squid source.. We are
using Squid version 2.5 STABLE 9. Is this a known issue on this version?
I tried searching on the release notes for this version and also on
Squid version 2.6 release notes but couldn't find any reference to this.
Can anyone please help us out on what might be the cause and help
resolve it.

Details of the crash is as below:
