Object lifetimes inside Lua (3.1)

[Cyril Zorin <cyril.zorin@...>]

Hullo =)

Are there any guarantees made with regard to the validity of pointers  
inside Lua code? That is, suppose we look at luaV_execute -- is the  
TProtoFunc* guaranteed to be valid after the luaV_execute call  
finishes, or are internal pointers (which are derived from  
lua_Object's) liable to be garbage collected like everything else?

Thanks,
Cyril.
