            Bug ID: 57311
           Summary: Conversion operator can be overloaded with itself by
                    using typedef
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Keywords: accepts-invalid
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org

This should be rejected:


typedef int Int;

template<class T, class U> struct is_same       { enum { value = 0 }; };
template<class T>          struct is_same<T, T> { enum { value = 1 }; };

struct X
{
    operator int() const { return 0; }
    operator Int() const { return 0; }
};

static_assert( is_same<Int, int>::value, "Int is int" );

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
If the definitions are not inline G++ spots the problems:

typedef int Int;

struct X
{
    operator int() const;
    operator Int() const;
};

X::operator int() const { return 0; }
X::operator Int() const { return 0; }



x.cc:10:1: error: redefinition of 'X::operator Int() const'
 X::operator Int() const { return 0; }
 ^
x.cc:9:1: error: 'X::operator int() const' previously defined here
 X::operator int() const { return 0; }
 ^

Fixed in GCC 8, I suspect by r8-2669 or r8-2664.
