[Bug c++/34196] [4.3 Regression] uninitialized variable warning in dead exception region

[pinskia at gcc dot gnu dot org]

This looks like a front-end/gimplifier bug.

So we have:
allocator::allocator();
try {
  char* a = s->c_str();
  t = string::string(a);
  try {
   b =  wtx-> unserialise (t);
   wt = AutoPtr::AutoPtr (b);
  } finnally {
    try {
      string::~string(t);
      } catch
      {
        AutoPtr::~AutoPtr (wt);
      }
  }
}
...


At the time we call ~AutoPtr, it does not have to be fully constructored.

I think this is related (and maybe even caused by) PR 15764.
