Squid: "Undefined symbol "_ZTVNSt3__117bad_function_callE" after upgrade to 2.8

I have the same issue after upgrading from 2.7.2 to 2.8.0.
When trying to start squid the below message is shown in syslog:

php-fpm[71339]: /pkg_edit.php: The command '/usr/local/sbin/squid -f /usr/local/etc/squid/squid.conf' returned exit code '1', the output was 'ld-elf.so.1: /usr/local/sbin/squid: Undefined symbol "_ZTVNSt3__117bad_function_callE"'

Hey that is familiar :

[2.8.0-RELEASE][admin@fw1.man.mylocal]/root: squid -z
ld-elf.so.1: /usr/local/sbin/squid: Undefined symbol "ZTVNSt3__117bad_function callE"

Hopefully it is resolved soon!

I also have this issue (tried upgrading this morning and had to roll back). No idea if this works as I can't try again until tomorrow.

This worked for me, but I don't understand why and if this lib can cause any problems later on.

KOM

@guilhermemulato That's why I'm not moving forward with 2.8.0 until they fix this issue.

@kom that did not resolve the issue for me. Seeing a few other 2.8 gremlins - might look to downgrade for a bit.

Apparently just uninstalling then reinstalling squid will fix this issue. The new squid cleans up files left behind by old squid.

Is this issue fixed if you reinstall squid after updating?

Before reinstalling, you need to move the library so that it's no longer present in /usr/lib (e.g. by running "mv /usr/lib/libc++.so.1 /root").

Hmm so should the order be
uninstall squid,
update pfsense + reboot
mv /usr/lib/libc++.so.1 /root
install squid

@aGeekhere

Yes, you can do it in the mentioned order.

KOM

@aGeekhere I just tried it. It does not fix the problem. I'm also not comfortable with the 'move lib somewhere else' fix as I don't know what side-effects it may have and I don't know how a future upgrade will handle it.

@KOM Has the issue been added to the bug tracker?

KOM

@aGeekhere No idea.

@aGeekhere

Update, will not be fixed as squid is deprecated from pfSense
