Option Name:coredump_dir
Default Value:Use the directory from where Squid was started.
Suggested Config:

# Leave coredumps in the first cache dir
coredump_dir /usr/local/squid/var/cache/squid

	By default Squid leaves core files in the directory from where
	it was started. If you set 'coredump_dir' to a directory
	that exists, Squid will chdir() to that directory at startup
	and coredump files will be left there.
