I'm afraid but then I think the only realistic way to
approach this is valgrind. All other alternatives involve
very long staring at code.

The good thing is -- this problem is likely be generic enough
that if you can reproduce your winbind version on a full
Linux distro including valgrind it should show up in a
similar way and then apply to your container.

Well, while raising a bug is a good thing for this. However
-- it's the same people who listen here who will work on
this and also ask for the valgrind output :-)

In your latest Mail I did not see a patch. Do you have a
reference to somewhere else?
