Segmentation fault while using `Authenticator::with_password` on musl.

[Wafelack]

PAM produces a segmentation fault when compiled using musl libc.

Code:

let mut auth = pam::Authenticator::with_password("<pam_config_name>").unwrap();

This line produces a segmentation fault on Void GNU/Linux with musl.

Same behaviour on my system using Alpine Linux.

Same here :(

Seems like this may be a pam-sys issue, as I'm seeing this for pam-client, which also uses pam-sys (version 1.0.0-alpha.3+).
