Howdy all, [ Excuse me if this is a known problem. I just (re)joined the list and Google did not show any obvious answers. ] I have a 2.6STABLE1 compiled/installed on a Solaris 10/SPARC machine. Squid frequently dies with a segment violation. I compiled Squid with --enable-poll and --enable-cache-digests options using Sun Studio 8. I tried compiling Squid with gcc 3.4.2, but it did not make any difference. I get the same problem. Below is the stack trace from the core file. It looks like state->current.key is NULL for some reason when the call to storeKeyScan is made. It looks like setting cache_vary to off helps. In any case, Squid should not crash. Your help would be appreciated.
