Apart from the fact that sshpass is a very dangerous package for your
security, and that you should prefer using public keys over using
sshpass, this seems to be not exactly a sshpass problem.  Rather it's a
change in the 1.7.10 Cygwin DLL which triggers this behaviour.

As a temporary workaround, try this patch to sshpass:
