4.8.2 belongs in a museum. If you want to perform some static analysis on trunk, you may find someone to look at the output, but with an old version I think you are wasting your time...
Comment 2 Jonathan Wakely 2018-09-10 11:05:44 UTC 
I looked at a few of these and they're complete nonsense.

This is not a redundant initialization in std::swap:

      _Tp __tmp = _GLIBCXX_MOVE(__a);
      __a = _GLIBCXX_MOVE(__b);
      __b = _GLIBCXX_MOVE(__tmp);

And the memory leaks are not leaks.
