Description Nathan Ridge

2011-02-21 02:57:54 EST

For the following code:

template <typename T>
class A {};

template <typename Functor>
void f(Functor functor)
{
    A<decltype(functor())> a;  // ERROR HERE
}

The parser gives the error: Invalid template arguments

The code compiles fine with gcc >= 4.3
