Re: AW: AW: AW: AW: AW: [squid-users] Squid 3.1.0.11 beta is available

Just break on SIGABRT and SIGSEGV. The actual place in the code where
things failed will be slightly further up the callstack than the break
point but it -will- be triggered.

Just remember to ignore SIGPIPE's or you'll have a strangely failing Squid. :)
