cache.log with debug_options set to just "ALL,1" (or default), right?

I cannot give you specific instructions, but you can try to find the
transaction that caused the crash by correlating packet capture with the
timing of the crash. If you are lucky, the transaction would not be
encrypted and will have few other transactions nearby. In that case, we
may be able to learn something from the transaction bytes received and
sent by Squid.
