RE: __gc metamethod bug

[Chris Cummings <chrisc@...>]

Doh! Missed that. Oh well - temporary fix:

        ld->PushObject(l);
        lua_getmetatable(l,-1);
        lua_setmetatable(l,-2);

:)

This is documented, specifically:

http://www.lua.org/manual/5.2/manual.html#2.5.1

"You mark an object for finalization when you set its metatable and the metatable has a field indexed by the string "__gc". Note that if you set a metatable without a __gc field and later create that field in the metatable, the object will not be marked for finalization. However, after an object is marked, you can freely change the __gc field of its metatable."
