As I mentioned earlier, this hasn't worked the because the debug symbols you're running gdb against don't quite match the binary in which the crash occurred. I would check the version of the debug symbols you're running gdb against versus the version of the squid binary that was installed. These changes can include patches and --configure changes, not just version changes of Squid. I'm not sure how debug symbols are "shipped" with packages in Debian - under CentOS for example they are shipped separately from the squid package, as squid-debuginfo-<version>.rpm.
