// Based on a testcase by Bryan Weston 

// egcs 1.1 fails to increment count

struct Base { Base() {} }; // removing the constructor fixes the problem

struct Derived : Base {}; // so does removing the base class

int main() {

  int count = 0;

  Derived* array[1]; // making this Base*[1] does not fix the problem

  array[count++] = new Derived (); // but then new Base() does

  if (count!=1)

    return 1;
