To replicate the crash, connect and disconnect a few times repeatedly in the lobby.
The offending memory access happens on the irc_stream struct in cl_irc.c. The Irc_Net_Disconnect function calls NET_StreamFree which might free the memory of the stream struct. However, the global irc_stream pointer keeps pointing to the same (freed) memory. The next time the connect function is called, it checks irc_stream for NULL, and if not, it calls NET_StreamFree again on it. That might cause a segfault if the memory was actually freed during the first call. It might not, because NET_StreamFree doesn't always free the stream (memory leak?), so you might need to repeat a few times to replicate the crash. The quick fix is to set the global irc_stream pointer to NULL after freeing the stream in Disconnect.
