 See below...

 No, this report should not be closed.
 
 The testcase compiled successfully because the line that causes trouble
 was commented out.  Please do read the comments.  I just checked it with
 version 20010217 and the uncommented line 10 still gives a parser error
 before `>' token:
 
 
 #include <utility> // defines pair template
 #include <iostream>
 using namespace std;
 
 typedef pair<int, int> ijpair;
 
 class foo {
 public:
     // this does not work,...
     foo( pair < int, int > ij = pair < int, int > ( 0, 0 ) ) : indices (ij) { }
     // ...but this does:
     // foo( pair<int,int> ij = ijpair(0,0) ) : indices(ij) { }
     void displayme() { cout << indices.first << ',' << indices.second << endl; }
 private:
     pair<int, int> indices;
 };
 
 int pairsum(pair<int,int> ij = pair<int,int>(0,0))
 {
     return ij.first+ij.second;
 }
 
 int main(void)
 {
     foo f1 = foo(pair<int, int>(42,7));
     foo f2 = foo();
     f1.displayme();
     f2.displayme();
     cout << pairsum() << endl;
     return 0;
 }
