[Bug c++/25325] New: GCC complains about private copy constructor, which must not be used at that point

[Serguei dot Kolos at cern dot ch]

The following code gives compilation error:

class NonCopyable
{
        NonCopyable( const NonCopyable & );
        NonCopyable & operator=( const NonCopyable & );
    public:
        NonCopyable() { ; }
};

void test( const NonCopyable & )
{ ; }

int main()
{
    test( NonCopyable() );
}
