What were the names of the functions that tolua4 generated?

I didn't follow the whole explanation, but you should know that 
operator==() was not supported on tolua4, but it is on tolua5, so maybe 
that's one thing that may be happening differently.

Try using lua_pcall instead of lua_call, that way you can use 
debug.traceback() to see the error message and a traceback.
