This would be the password expiry warning in pam_winbind.

However I'm sceptical of the versions given, there are just no relevant
changes, but if it is - as the description appears - an un-initialised
variable then just a rebuild might have broken it.  

The next step would be to trace this in a debugger on both the
pam_winbind and winbindd side, also checking if somehow the structure
is being misread - eg 64 bit time on one side and 32 bit time on the
other.
