            Bug ID: 63959
           Summary: G++ misreports volatile int as trivially copyable
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lh_mouse at 126 dot com

The type trait std::is_trivially_copyable<volatile int>::value yields true on
g++ (GCC) 5.0.0 20141119 (experimental).

ISO C++ states that volatile types are NOT trivially copyable:

N3936 3.9 Types [basic.types]
9 Arithmetic types (3.9.1), ... Cv-unqualified scalar types, trivially copyable
class types (Clause 9), arrays of such types,
** and nonvolatile const-qualified versions of these types (3.9.3) **
are collectively called trivially copyable types. ...

So this is a bug. Please fix.
