             Bug #: 11295
           Summary: An explicitly defaulted constructor makes the class
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: max at duempel.org
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

The following example should render a trivial type, because the constructor is
explicitly defaulted, which should be equal to the constructor not being
mentioned at all:

struct Foo { Foo() = default; };
#include <type_traits>
static_assert(std::is_trivial<Foo>::value, "Foo");


test.cxx:3:1: error: static_assert failed "Foo"
static_assert(std::is_trivial<Foo>::value, "Foo");
