SYMPTOMS

When a function template is defined without one of the types in the template parameter list in its function argument list, the Visual C++ compiler issues the following error:

   fatal error C1001: INTERNAL COMPILER ERROR
       (compiler file 'msc1.cpp', line 1090)

RESOLUTION

The argument list of a function template needs at least one argument using a type specified in the template parameter list. This is a requirement of the Visual C++ language.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.

MORE INFORMATION

Sample Code

   /* Compile options needed: none
   */ 
   // The function "func" should use T or some variant of T in
   // its argument list. The following code produces the C1001 error.
   struct myclass {};
   template <class T> T* func(int p) { return 0; }
   void main(){
     myclass *x = func(0);
   }
