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

• The Microsoft C/C++ Compiler (CL.EXE),
  • Microsoft Visual C++ 32-bit Edition, versions 2.0, 2.10, 2.20

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
*/ 

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

class B
{
  public:
  A GetClassA();
};

void main()
{
  B b;
  b.GetClassA().problem(10);
}
