I think I found a bug ...

[Jan Metzger]

Here is the program bug.cc:
---------------------------------------
class AClass
{
 public:
  static const unsigned int data_size;

  double data[data_size]; 
  AClass(void);
  AClass(const AClass& p);

};

const unsigned int AClass::data_size = 5;

AClass::AClass(void) 
{ }

AClass::AClass(const AClass& p)
{
  for (int i=0; i<data_size; ++i)
    this->data[i] = p.data[i];
}
-------------------------------------------
trying to compile this with
> g++ -v --save-temps bug.cc
produces the following output:
