Most likely not winsock. The reason for this claim ?
Well, I tried this with a dedicated Q2 server, and this one doesn't
crash, instead it reports:
NET_GetPacket: WSAEMSGSIZE
A dedicated unreal server reports the same:
Log: UDP recvfrom error: WSAEMSGSIZE
So it seems that winsock reports an error, but QW doesn't handle it
properly.
(All tests done on NT4/SP4).
