[Bug 1257186] Re: memory leakage messages (no talloc stackframe)

[CaesarS]

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                        pam_smbpass.so 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 ***
Aborted

Which happens after the password is entered.

  development branch):

  no talloc stackframe at ../source3/param/loadparm.c:4831, leaking
  memory

  From this upstream bug report, I am lead to believe the issue is in
  libpam-smbpass, but I don't really know for sure.

  I am filing this bug report mainly so that I can refer to it on the
  testing tracker as an issue, while still setting the test case to
  pass. Note that other than the error message itself, I am not aware of
  any bad side effect.
