That's what puzzles me a lot.  The cygdrive prefix should never have been
converted to a valid Win32 path.  Not according to your mount

At this point something goes wrong, but unfortunately it's not clear
from the strace output what that is.  The created file handler is one
for disk-based files, rather than a cygdrive handler.

This is bad as well.  If your directory D:\cygwin\cygdrive really exists,
you shouldn't see such an error (STATUS_INVALID_HANDLE).  Very strange.

This looks insuspicious.

This might be the problem, but I have no own experience with the potential
problems arising from using these tools.
