VS 2003 (and 2005 Express) do not produce any diagnostics for this

private:
   test( bool );
    operator bool();
    operator const bool();

class test2

public:
    test2( int );
    test2( bool );

void f()
{
    test t2( 10 );
    test2 tt( t2 );
}

IMO, the

    operator const bool();

in itself should produce a diagnostic.

Why? What diagnostic do you expect? On what grounds? It's just
a repeat declaration of the same operator bool(). The top-level
'const' does not matter.

You might argue that a warning is warranted here, but no diagnostic
is *required* by the Standard.

Second issue is the

test2 tt( t2 );

should result in the ambiguity.

Yes, it should.

Removing the questionable

operator const bool();

the code (as expected) doesn't compile on the tt( t2 ) line.

That's rather strange.

Yes, you are correct.

You need to submit this as a bug report, if it hasn't been already
discovered:
