FIX: C1001 When Initialize Array of Type Class with #include

• Microsoft C/C++ Compiler (CL.EXE), used with:
  • Microsoft Visual C++ 32-bit Edition, versions 4.0, 4.1, 4.2

SYMPTOMS

When you initialize an array of a user-defined type using an include file (see the example in this article), the compiler generates this error:

fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 899)

RESOLUTION

There are two workarounds as described below.

• Add a comma after the last element in the include file.


-or-


• Compile the .cpp file with the /P compiler option. This generates a file with a .i extension using the same base name as the .cpp file. Rename the file so that it has a .cpp extension, and compile it, or simply compile the .i file using the /Tp compiler option.

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

.cpp File
---------

   // To reproduce the error, compile options needed: none
   // Define WORKAROUND to use workaround #1

   struct CMemTblMgr {
       CMemTblMgr(int);
       ~CMemTblMgr(void);
   };

   CMemTblMgr sm_mgrLst[] = {
   #include "CMEMTABL.INC"
   };

Cmemtabl.inc File
-----------------

   #ifndef WORKAROUND
      CMemTblMgr(1),
      CMemTblMgr(2)

   #else
      CMemTblMgr(1),
      CMemTblMgr(2),
   #endif
