--- Comment #7 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-11-07 11:05:20 UTC ---
Patch is reverted for now. The fix wasn't correct (or was incomplete), as
showed by the testcase:

class nullable_int
{
  bool init_;
  union {
    unsigned char for_value_init;
    int value_;
  };
public:
  constexpr nullable_int() : init_(false), for_value_init() {}
};

int main()
{
  nullable_int n;
}
