            Bug ID: 202120
           Summary: pam_ck_connector.so causes login to crash on i386
           Product: Base System
           Version: 10.1-STABLE
          Hardware: i386
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: anindya49@hotmail.com

I can cause /usr/bin/login to segfault in a predictable manner on i386. I
discovered this while trying to enable consolekit through pam, by adding the
following line in /etc/pam.d/login

session  optional  /usr/local/lib/pam_ck_connector.so debug nox11

After this, any attempt to log in from the text console causes the system to
drop me back to the login prompt, and the system log /var/log/messages says
that login exited with signal 11.

uname -a:
FreeBSD turing 10.1-RELEASE-p16 FreeBSD 10.1-RELEASE-p16 #0: Tue Jul 28
11:41:12 UTC 2015    
root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  i386

freebsd-version
10.1-RELEASE-p16

I have tested this on multiple i386 machines. The error is also present in
10.2-RC2. I upgraded one of my i386 machines for testing.

The error does not occur on x64 machines. Login is successful, and
ck-list-sessions shows an active session on the console, again tested on
multiple machines. So it seems an i386 issue.

Hope I was thorough enough. Thanks for looking into it.
