            Bug ID: 58194
           Summary: default argument for constructor outside of class DR
                    1344
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dushistov at mail dot ru

Such simple code accepted by gcc 4.8.1:

struct Foo {
    Foo(const char *);
};

Foo::Foo(const char *str = 0)
{
}

There is DR 1344 about it:

http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#1344

and according to disscussion in clang mailing list:

http://clang-developers.42468.n3.nabble.com/Reason-for-Diagnostic-on-default-ctors-redeclaration-td4032117.html

Quote:

This was last discussed by WG21 at the Bloomington meeting. Notes from there:

  "Consensus: Make this ill-formed as suggested in the write-up. Core issue
1344. Priority 0, Doug drafting."

So it would be nice, if gcc emit error on such bad code.

The issue is still in drafting status, thus I'm suspending this.

Unsuspending, this is now C++14
