The information in this article applies to:

- The C/C++ Compiler (CL.EXE), included with:
   - Microsoft Visual C++, 32-bit Editions, versions 4.0, 4.1

   - Microsoft Visual C++, 32-bit Professional Edition, version 4.2 
-------------------------------------------------------------------------------

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);
     }
