Sry for the double post but it looks like an buffer overrun in the CinputHack function im investigating.

This looks kinda strange why this long buffer value in the backtrace seems like someone is sending specific packets.

void (CInputMain * const, LPCHARACTER, const char* (a3))
{
[...]
strlcpy(&v7, a3 + 1, 256);
}
Maybe a3 is to big for this 256 byte buffer anyway what is this line so i removed it completely because it doesnt get used afterwards
v7 is not referenced anywhere.

Maybe the best would be to remove the entire function, since we dont need it.
