Description Antti Mäkelä 2010-05-04 06:22:39 UTC

When a NSC TCP socket is in listening state and accepts a connection, during the for txbuffersize will be uninitialized in the new (forked) socket.

This eventually crashes at Assert on line 367 in GetTxAvailable, since it can be anything.

I added m_txBufferSize = sock.m_txBufferSize; to the copy constructor and problem seems to have gone away.
