I think I found the cause.  ldd utilizes the Win32 debugging API.
For some reason I don;t know, loading the cygkdb5-7.dll emits
an exception STATUS_ENTRYPOINT_NOT_FOUND which hasn't been handled
by ldd yet.  Instead it ran in an endless loop.

I fixed this in the git repo and I've just uploaded new developer
snapshots to https://cygwin.com/snapshots/

You don't have to install the full package, there was only a change to
usr/bin/ldd.exe, which should run under any recent Cygwin DLL.  Please
give it a try.


Thanks,
Corinna
