Looks like WS2_ConnectEx is at fault.
It is being called with a sendBuf of NULL which results in n_iovecs and
first_iovec being set to 0 resulting in a len of 0.
I see no evidence of checking for this case along that codepath.

This should never happen. We should always have at least one iov at that
point, the callers should make sure of that.
