Error occurs after pin for the PIV card is entered into the GNOME login GUI.
Error in /var/log/messages:
gdm-session-wor[23783]: segfault at 0 ip 00007f3e851589ab sp 00007ffd2e747300 error 6 in libcrypto.so.1.1[7f3e84f6a000+29b000]

Remove "crl_online" from cert_policy in /etc/pam_pkcs11/pam_pkcs11.conf
and there is no segmentation fault.

openssl 1.1.1-1ubuntu2.1~18.04.5
opensc 0.17.0-3
libpam-pkcs11 0.6.9-2build2

Using opensc pkcs11_module.
Smartcard has a CRL URL set with FQDN and the prefix of the URL is http://.
This did not exist in Ubuntu 16. This started in 18.04 (first release) and has existed in all minor versions of 18.
