You mean beyond the obvious course of action (i.e. debugging)?  Well, I'd
recommend checking 1.5.10 since it's the current release.  If that doesn't
resolve the issue, I suppose you could try a snapshot to see if the problem
has been caught and resolved after the release (though you may see other
problems since snapshots at this point are the result of active and ongoing
development, with very little testing).  Otherwise, your best bet is to 
build the Cygwin DLL and debug into it as needed.
