[Bug libstdc++/14648] New: hash_maps are broken (regression)

["schmid at snake dot iap dot physik dot tu-darmstadt dot de" <gcc-bugzilla at gcc dot gnu dot org>]

hash_maps no longer work. This is a regression with respect to gcc 3.4.0 built 
last week. 
 
Consider the following code: 
 
source code th.C 
 
#include <ext/hash_map> 
#include <ext/rope> 
 
using namespace std; 
using namespace __gnu_cxx; 
 
int hmap1_test(int, char**) 
{ 
  typedef hash_map<char, crope, hash<char>, equal_to<char> > maptype; 
  maptype m; 
  m['l'] = "50"; 
  cout << "m['x'] = " << m['x'] << endl; 
  return 0; 
}  
 
g++ -v -W -Wall th.C
