Thanks.

The culprit are apparently some weird User and Group SIDs.

Granted, it's not nice of Cygwin to SEGV here, but I do wonder where
the SIDs S-1-81-0-0 and S-1-0 are coming from.  They are both invalid
as far as I can see.

Hmm.  The problem is to reproduce this to find out where this happens.
The exception address is inside a Windows DLL :-P
