[luabind] Crash with overloaded functions.

[Jens E. <jeg...@la...>]

Hi

I am using a CVS version which is about two days old but I am experiencing
some crashing.

Firstly I constantly experience crashes whenever LuaBind is searching for an
overloaded function (in a class) which does not exist. Could anyone please
tell me if this is a known bug in the current CVS version.

Secondly I have experienced another bug which I suspect may be related.

I have three class of the kind:

// An abstract class
class A {
	...
	void doSomething() = 0;
}

// a class B which is derived from A:
class B : public A {
	void doSomething() {
		...
	}
}

// a class C which is derived from B:
class C : public B {
	...
	void doMore() {
		...
	}
}

All three clases have been integrated in LuaBind:

	luabind::class_<A>(lua, "A");

	luabind::class_<B, A>(lua, "B")
		.def(luabind::constructor<>())
		.def("doSomething", &B::doSomething);

	luabind::class_<C, B>(lua, "C")
		.def(luabind::constructor<>())
		.def("doMore", &C::doMore);

Unfortunately LuaBind crashes during binding. The call-stack from VC is:

00000001()

boost::function2<int,struct lua_State *,void *,int>::assign_to_own(class
boost::function2<int,struct lua_State *,void *,int> const &) + 79 bytes

boost::function2<int,struct lua_State *,void *,int>::function2<int,struct
lua_State *,void *,int>(class boost::function2<int,struct lua_State *,void
*,int> const &) + 44 bytes

luabind::detail::overload_rep::overload_rep(struct
luabind::detail::overload_rep const &) + 56 bytes

luabind::detail::class_rep::add_base_class(const
luabind::detail::class_rep::base_info & {...}) line 794 + 12 bytes

luabind::class_base::commit(struct lua_State *) + 1014 bytes

luabind::class_<class C,struct luabind::bases<class B,class A,struct
luabind::detail::null_type,struct luabind::detail::null_type>,struct
luabind::detail::unspecified,struct
luabind::detail::unspecified>::~class_<class C,struct luabind::bases<class
B,class A,struct luabind::detail::null_type,struct luabind::d + ...

I seems that j At line 794 in class_rep.cpp is invalid.

Could tell me if I am binding correctly and if this is a known bug in
LuaBind?
