Wow, this bug has a long history.

I can confirm the issue as well with 4.1.6 and 4.2.1 I've isolated to the line:

auth optional migrate

Configured in /etc/pam.d/common-auth

That line is added by libpam package installation and also by using pam-auth-update to enable SMB Password Synchronization

For 4.2.1 the error however occurs in su:

*** Error in `su': double free or corruption (fasttop): 0x000000000110d800 ***

Which happens after the password is entered.
