           Summary: __has_trivial_constructor doesn't work for void and
                    arrays of unknown bound
           Product: clang
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: hhinnant at apple.com

This trait is supposed to work for void types, and arrays of unknown bounds.  I
believe it should answer false to both.  Here is a test case I believe should

template <class T, bool Result>
    static_assert(__has_trivial_constructor(T) == Result, "");
    // or use assert if -std=c++0x not specified

int main()
    test__has_trivial_constructor<void, false>();
    test__has_trivial_constructor<int[], false>();
