Hi,

I found a clang crash that seems to be caused by this patch. Here's a reduced
test case:

  template <class>
  class a {
   public:
    ~a();
    void b();
  };

  template <class c>
  a<c>::~a() try {
    b();
  } catch (...) {
  }

  class d {
   public:
    d(const char *, int);
    a<int> e;
  }

  d("", 1);

Building it with `clang -c -frounding-math` results in crash:
