[Bug c++/15764] no cleanup if temporary's dtor terminates with an exception

------- Comment #9 from jason at gcc dot gnu dot org  2007-09-06 05:36 -------
This version of the test breaks under ICC:

----------------------
extern "C" void abort ();

int counter = 0;
int thrown = 0;
struct a {
  ~a () { if (!thrown++) throw 1; }
};

int f (a const&, const a&) { return 1; }

struct b {
  b (...) { ++counter; }
  ~b ()   { --counter; }
};

void g();

int main () {
  try {
    b tmp(f (a(), a()));
  }
  catch (...) {}

  if (counter != 0)
    abort ();
}
----------------------

For whatever reason, if the first ~a throws, ICC doesn't try to destroy tmp,
but if the second ~a throws, ICC cleans up tmp properly.  Odd.
