FIX: C1001 Internal Compiler Error in MAIN.C File Line 374

The information in this article applies to:

• The Microsoft C/C++ Compiler (CL.EXE), included with: Microsoft Visual C++ 32-bit Edition, versions 2.0, 2.1, 2.2

SYMPTOMS

Defining a static member function together with a user-defined class destructor in a class that is used only as a return type of a member function in another class may cause the Microsoft C++ compiler version 9.0 to generate the following compiler error:

   fatal error C1001: INTERNAL COMPILER ERROR
   (compiler file 'd:\b_bld\c2.m2\p2\main.c', line 374)
   Please choose the Technical Support command on the Visual C++
   Help menu, or open the Technical Support help file for more
   information

RESOLUTION

To work around the problem, use one of the following suggestions:

• Instead of using the chain notation to call the static member function, break the statement into two statements. For example,

        b.GetClassA().problem(10);     // error
  
        a = b.GetClassA();             // work-around
        a.problem(10);
  
     where a is an instance of class A, b is an instance of class B
     based on the sample code below.
  
     -or-
  
  

• Define the static member function as a non-static member function.

  -or-

• Instead of returning object A for function GetClassA() in the following sample code, return a reference to A.

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 Microsoft Visual C++, 32-bit Edition, version 4.0.

MORE INFORMATION

The sample code below can be used to generate the C1001 error.

Sample Code

/* Compile options needed: none
*/

  public:
  ~A() {}
  static void problem(int a) {}

class B {

  public:
  A GetClassA();

void main()

  B b;
  b.GetClassA().problem(10);
