Consider the following program

-------------------------------------
#include <stream.h>

class A {
private:
  int a;
public:
  A() { cout << "A()\n"; a = 1; }
  A(int i) { cout << "A(int i) " << i << "\n"; a = i; }
  ~A() { cout << "~A() " << a << "\n"; }
};

int
main() {
  A a;
  A b[3] = {4, 5};  // array has 3 elements, but only 2 initilizers !
}
-------------------------------------

According to C++ 2.0 Ref. Man. p. 81:
  "Arrays of objects of a class with constructors use constructors in the 
  initilization just like individual objects. If there are fewer objects in the
  list than elements in the array, the default constructor is used."

Here is what I get as output:
  A()
  A(int i) 4
  A(int i) 5
  ~A() 0
  ~A() 5
  ~A() 4
  ~A() 1

NO CONSTRUCTOR CALLED AT ALL!!!
The correct output should be
  A()
  A(int i) 4
  A(int i) 5
  A()
  ~A() 1
  ~A() 5
  ~A() 4
  ~A() 1

Compiler: g++ version 1.36.4 (based on GCC 1.36.93)
Lib:      libg++ 1.36.2
