I am running the g++ from interviews of December 21
on a sun-4.  The program below constructs an "X" only when
the if condition is satisfied, but it mistakenly destructs
it regardless.  Enclosing the for statment in braces is a
workaround.  Cfront behaves correctly.

#include <stream.h>

class X {
  int a;
public:
  X() : a(123) {}
  X(int n) : a(n) {}
  ~X() {cout << "Deleting " << a << "\n";}
};

main(int ac)
{
  if (ac > 1)
    for (X x(5); ac > 0; ac--);
}
