SYMPTOMS
When you declare a global typedef of any STL iterator, the compiler error C2955 occurs.



RESOLUTION
In the sample code below, replace: typedef IntVector::iterator IT ; with the following code: // Workaround for VC++ 4.2: #if _MSC_VER == 1020 struct X  { typedef IntVector::iterator it ; };  typedef X::it IT ; #else typedef IntVector::iterator IT ; #endif



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.



Sample Code
/* Compile options needed: /GX */   #include #include typedef vector  IntVector; // C2955 error on the following line typedef IntVector::iterator IT ; void Show (IT i)  { cout << *i << endl; }  int main (int argc, char *argv[]) {      IntVector   v;       v.push_back(1); v.push_back(2); v.push_back(3); for (IntVector::iterator i = v.begin; i != v.end; i++) {          Show(i); }      return 0 ; }
