--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-01-27 11:09:50 UTC ---
For this variation where f<T> is not deduced, 4.4 says "sorry, unimplemented"
but doesn't ICE, 4.5 and 4.6 ICE in the same place:

template < typename T >
int f( const char * );

template<int> struct N { };

template < typename T >
N<sizeof( f<T>( "" ) )> g( const T &t );

void h()
{
    g( 0 );
}
