[Bug c++/36490] New: Attempt to copy a temporary object during passing it to a function as a const reference

["dervih at interia dot pl" <gcc-bugzilla at gcc dot gnu dot org>]

gcc returns:
niko.cpp: In function 'int gun()':
niko.cpp:7: error: 'A::A(const A&)' is private
niko.cpp:20: error: within this context

when compiling:

struct A {

   A() ;
   int fun() const ;

private:
   A( const A& ) ; 

} ;


int  hun( const A& a ) {

    return a.fun()*4 ;
}


int gun() {

  return 4+5*hun(A()) ;

}

MSVC 2008 and COMEAU compile this program flawlessly.
