Oh I see. You're right then, although this is not what the HPB_bot does (and neither most of the bots derived from it).

Another thing: sizeof (enginefuncs_t) vary between each successive version of the interface. When you memcpy them, you have to ensure you memcpy the right amount of function pointers. And for this you HAVE to update your header files, if not your source code. So all in all that error will persist if you don't do anything about it.
