Squid authenticator crashes on sign-in

Hey guys,

i've set up a new root server in france and installed squid on it to bypass the youtube-restrictions and other stuff here in germany.
the problem is, that every time i try to sign-in the authenticator process (basic_ncsa_auth) crashes due to a segfault in libc.

journatctl shows this

Feb 17 16:25:41 **hidden** kernel: basic_ncsa_auth[21752]: segfault at 0 ip 00007fce4e0d457a sp 00007fff51c6cbc8 error 4 in libc-2.17.so[7fce4dfaa000+1a4000]
Feb 17 16:25:41 **hidden** squid[21747]: WARNING: basicauthenticator #1 exited
Feb 17 16:25:41 **hidden** squid[21747]: Too few basicauthenticator processes are running (need 1/20)
Feb 17 16:25:41 **hidden** squid[21747]: Starting new helpers
Feb 17 16:25:41 **hidden** squid[21747]: helperOpenServers: Starting 1/20 'basic_ncsa_auth' processes
Feb 17 16:25:41 **hidden** systemd-coredump[21985]: Process 21752 (basic_ncsa_auth) dumped core.

the dumped core stuff includes usernames and password-hashes so i will not post them here.
i've tried several squid versions (3.2.3-1, 3.2.6-2, 3.2.7-2, 3.3.1-1) but none of them works. on my old machine (with glibc and squid not updated to the latest version) it works as expected.

any ideas what to do next or a hint what it could be?

thanks in advance
