Her fix should be in the > latest snapshot at http://cygwin.com/snapshots/ Just FYI, I found that the Winsock function WSARecvFrom has a weird property. If the parameter in which the socket name is returned is a NULL pointer, the namelen pointer must be a NULL pointer as well, otherwise WSARecvFrom returns a WSAEFAULT error, even if the namelen pointer points to a valid, writable memory area. The name and namelen parameter are ignored entirely with TCP sockets, so WSAEFAULT is only returned for UDP sockets. This might explain that we didn't have a bug report for this so far. Thanks for the testcase, even though an entire application is quite bulky as a testcase.
