: Search converges between 2004-07-29-trunk (#498) and 2004-07-30-trunk (#499).
Reduced testcase every where:
int subtrees = 4;
template< class T >
struct Tree {
  Tree* L[subtrees];
  Tree* R[subtrees];
  ~Tree()
  {
    delete [] L[0];
    delete [] R[0];
  }
};

void f()
{
        Tree<int> t;
}


Note the following is a 4.0 regression though:
int subtrees = 4;
template< class T >
struct Tree {
        Tree* L[subtrees];
        Tree() { }
};
void f()
{
        Tree<int> t;
}


Also this is invalid code as int *L[variable]; should have been rejected as variable is not constant, note 
(at least on the mainline) we reject it for non templates.
