2.1.6 Segfault (unlang: if (NAS-Port == 0) { reject }

[Michael Bryant]

Hi,
Reproducible on 2.1.6, default config with:
These lines in the authorize section:
       if (NAS-Port == 0) {
                reject
        }

And this command:
echo "User-Name = test" | radclient 10.252.24.114 auth testing123

An Access-Request packet not containing the NAS-Port Attribute causes the server
to segfault.

Cheers
--Mike

P.S.
Workaround: if (NAS-Port && NAS-Port == 0) {
