Glad you have a working "sanity check" test! I agree with FreeBSD forum 
folks that you have proven that your OS does have core dumps enabled (in 
general). Now we need to figure out what is the difference between that 
working test script and Squid.

Please start Squid from the command line, with -N command line option 
(among others that you might be using already), just like you start the 
"sanity check" test script. And then kill Squid as you kill the test script.

If the above does not produce a Squid core file, then I would suspect 
that Squid runs as "squid" user while the test script runs as "root". 
Try starting the test script as "squid" user (you may be able to use 
"sudo -u squid ..." for that).

If same user does not expose the difference, start the test script from 
the directory where you told Squid to dump core.


HTH,

Alex.
