Thanks for the testcase.  It took some time to reproduce it (actually
the error occured with quite different result on my machine) and to track
it down, but I think I have found the culprit, an uninitialized variable
in the socket sendto/sendmsg code.  After having initialized it to 0, I'm
now unable to get your example to fail.
Or better: http://cygwin.com/acronyms/#WJFFM :-)

Could you please try the next snapshot from http://cygwin.com/snapshots/
to see if it solves the problem for you?


Thanks,
Corinna
