I have this kind of code :

#include <Core/Core.h>
using namespace Upp;

CONSOLE_APP_MAIN
{
	VectorMap<String, unsigned int> test;
	
	test.Add("t1") = 2;
	try{
		//Work correctly
		Cout() << test.Get("t1") << EOL;
				
		//Raise assertion in debug mode
		//Print 23 in release mode (CLANGX64)
		//Print 0 in release mode (MSVS19x64)
		Cout() << test.Get("t2") << EOL;
	}catch(Exc& e){
		Cout() << e << EOL;
	}catch(...){
		Cout() << "Catched" << EOL;
	}
}

For Strange reason, test.Get("t2") print 23 in release mode when using CLANGx64, why ?
