Hello:

the code below does not work as expected when compiled with MSC compiler, tested with MSC10/WinXP and MSC12/Win7:


#include <Core/Core.h>

using namespace Upp;

class A 
{
public:
	int x;
	A():x(0)             	{}

	A( A rval_ a) 			{ LOG("from A");x = a.x;}
	A(String const &s) 		{ LOG("from String");}
	operator String() 		{ LOG("to String"); return ""; }
};

A GetA()
{
	A a;
	a.x = 6;
	return a;
}

CONSOLE_APP_MAIN
{
	A a = GetA();	
	DUMP(a.x);
}
 


the output of this test case is :


from A
to String
from String
a.x = 1310556





regards
omari.
