Reduced testcase:
namespace a
{
  class basic_stringstream  {};
  typedef basic_stringstream istream;
  typedef basic_stringstream stringstream;
}
using namespace a;
void PerformTest02 ()
{
  struct Manipulators 
  { 
    static istream & IgnoreSpace (istream & anInputStream) {}
  };
  stringstream objStream;
  Manipulators::IgnoreSpace(objStream);

[Bug debug/32507] [4.1 regression] ICE with typedef in local class

[reichelt at gcc dot gnu dot org]

------- Comment #3 from reichelt at gcc dot gnu dot org  2007-12-27 16:30 -------
The bug appeared in GCC 4.0.0, but is already fixed on the 4.1 branch, on the
4.2 branch (in version 4.2.1) and on mainline.
