luabind: problem retrieving values from table indexed by non-built-in classes

Hi,
I'm using luabind 0.9.1 from Ryan Pavlik's master distribution with Lua 5.1, cygwin on Win XP SP3 + latest patches x86, boost 1.48, gcc 4.3.4. Lua and boost are cygwin pre-compiled versions.
I've successfully built luabind in both static and shared versions.
Both versions pass all the tests EXCEPT for the test_object_identity.cpp test which fails in both versions.
I've tracked down the problem to the following issue:If an entry in a table is created for NON built-in class (i.e., not int, string, etc), the value CANNOT be retrieved.
Here's a code piece that demonstrates this:
#include "test.hpp"#include <luabind/luabind.hpp>#include <luabind/detail/debug.hpp>
using namespace luabind;
struct test_param{	int obj;
};
void test_main(lua_State* L){	using namespace luabind;
	module(L)	[		class_<test_param>("test_param")			.def_readwrite("obj", &test_param::obj)	];
	test_param temp_object;	object tabc = newtable(L);	tabc[1] = 10;	tabc[temp_object] = 30;
	TEST_CHECK( tabc[1] == 10 );              // passes	TEST_CHECK( tabc[temp_object] == 30 );    // FAILS!!!
}
tabc[1] is indeed 10 while tabc[temp_object] is NOT 30! (actually, it seems to be nil)
However, if I use iterate to go over tabc entries, there're the two entries with the CORRECT key/value pairs.
Any ideas?
Thx,David
