[Samba] S4-Winbind dumping core on password

I'm still having the issue that password authentication to a domain account appears to cause sernet-samba-winbind to dump core. I've attached output from reproducing the error with "valgrind --trace-children=yes winbindd", but this time with the debuginfo package installed (which appears to give more informtaion). Help getting samba-4.1 working in our AD environment would be much appreciated.

To follow up, I've tried with later versions of sernet-samba-4.0, and today with sernet-samba-4.1.1. The issue persists.
No problems logging in from windows with gssapi, and using services with credentials from the ticket cahce -- ssh, smbclient -k, etc. work just fine. Logging in with a password, sudo su, etc. all fail on password exchange between pam and winbind.
Thanks for looking into this,

The attached captures the output from valgrind as requested, for two failed attempts to "sudo su" with password from a domain account. (I tried adding the '-v' option to valgrind to display the "suppressed" errors, but that didn't have the desired effect.)
Let me know if there's more I can add, and I'll do my best to get you the information.

Are you able to reproduce this with winbindd running under valgrind?
valgrind --trace-children=yes winbindd
