That was the essential information to find the bug.  For the last
Cygwin version I added support for the new ReFS filesystem and I
changed one datastructure without also changing another, closely
related datastructure.  The bug would have shown for other FSes
as well, but it would only have resulted in printing the wrong
FS type in mount.  Only for NcFsd it was bound to crash.

This will be fixed in the (soon to come) Cygwin 1.7.17.
