           Summary: [C++0x] ICE on instantiating decltype(expr)::type with
                    template

ICE on instantiating the following two template functions.
I tested with GCC 4.7.0 20110801.

---- 8< ----
template < typename T >
auto
f1( T x ) // ICE on here
  -> typename decltype( x )::type {}

template < typename T >
typename decltype( T{} )::type
f2( T x ) {} // ICE on here

struct S { typedef void type; };

void g()
{
    f1( S() );
    f2( S() );
}
