Is there a bug logged for this issue - could only find something logged on 3.0pre3 - (bug 879) but it says that it was fixed for final release version. Is this a known issue?

You are the first to hit it again since then.
Is your squid patched with old patches written prior to 3.0 perhapse?

There should be a core dump sitting around from the crash which you can
use to figure out what the real problem behind the crash is. You need to
know that to find a workaround or fix.
