FIX: Debugger Hangs When Very Long STL Symbol in Watch Window

MORE INFORMATION

Steps to Reproduce Behavior

Build the following sample code as a Console application:

   #include <windows.h>
   #include <map>
   #pragma warning (disable : 4786 )
   using namespace std;
   template<typename Type>
   class SomeReallyLongSymbolName
   {
       public:
         SomeReallyLongSymbolName(Type var){m_Type = var;}
         SomeReallyLongSymbolName(){}
         void func(Type var){m_Type = var;}
         Type m_Type;
   };
   SomeReallyLongSymbolName<int> intObject(0);
   typedef map< DWORD, SomeReallyLongSymbolName< DWORD> >
   STLTypeWithLongName ;
   STLTypeWithLongName  STLObjectWithLongName;
   int main()
   {
      intObject.func(1);
      return 0;
   }
				

After the build is complete, start the debugger by pressing the F10 key. In the Watch Window, enter the two variable names, intObject and STLObjectWithLongName. You will be able to expand the intObject variable. However, when you try to expand the STLObjectWithLongName variable, the Debugger will hang.
