If you can get it to produce core dumps that is easiest. The usual gdb
analysis of the core gives trace and state details.

Otherwise you have to attach gdb to the running worker by PID number.
Workers log their PID to cache.log during the startup sequence, or you
can pick one from the system process listing (ps).

For that matter what is the cache.log entries produced by the
worker/kid as it died?

It means Squid is not able to identify any cache_peer entries or DNS
A/AAAA records which can be used to fetch that URL.
