You tested under linux, right ? Used 65 or 67 ?

Also tested in a friend server, it crash immediately after you restart the server. Idk what can I do wrong. What I do is:
1. Start the HLDS
2. It works correctly, hook is called, function is found.
3. Change map/do a restart
4. Server crash with the error I have posted.

Hooking a non-virtual function works fine for example.
