Last reviewed: July 24, 1997
Article ID: Q133068

The information in this article applies to:

The Microsoft C/C++ Compiler (CL.EXE) included with: - Microsoft C/C++ version 7.0 - Microsoft Visual C++ for Windows, versions 1.0, 1.5, 1.51, 1.52 - Microsoft Visual C++, 32-bit Edition, versions 1.0, 2.0, 2.1, 4.0,
```
     4.1, 4.2, 5.0
```

SYMPTOMS

The sample code fragment listed at the end of this article incorrectly deletes a typedef of a pointer to a structure, which generates the following compiler errors:

- For Visual C++ 5.0 for Windows NT:

     fatal error C1001: INTERNAL COMPILER ERROR
     (compiler file '.\toil.c', line 3645)

For Visual C++ 4.2 for Windows NT:

      fatal error C1001: INTERNAL COMPILER ERROR
      (compiler file 'toil.c', line 4094)

For Visual C++ 4.1 for Windows NT:

      fatal error C1001: INTERNAL COMPILER ERROR
      (compiler file 'toil.c', line 4051)

For Visual C++ 4.0 for Windows NT:

      fatal error C1001: INTERNAL COMPILER ERROR
      (compiler file 'toil.c', line 3128)

For Visual C++ 2.x for Windows NT:

      fatal error C1001: INTERNAL COMPILER ERROR
      (compiler file 'toil.c', line 2847)

For Visual C++ 1.0 for Windows NT:

      fatal error C1001: INTERNAL COMPILER ERROR
      (compiler file '@(#)main.c:1.82', line 289)

For Visual C++ version 1.5x for Windows:

      fatal error C1059: compiler is out of near heap space

For Visual C++ version 1.0 for Windows:

      fatal error C1063:

For C/C++ version 7.0:

      fatal error C1001: INTERNAL COMPILER ERROR
      (compiler file '2pass/getattr.c', line 346)

RESOLUTION

The above error messages are misleading and do not point out the real problem, which is that you cannot delete a typedef. Additionally, the operand of delete must be a pointer returned by the new operator. Using delete on a pointer to an object not allocated with new gives unpredictable results.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Sample Code to Reproduce Problem

   /* Compile options needed: none
   */

   typedef struct {
      int x;
   }MY_STRUCT, *LPMY_STRUCT;

   LPMY_STRUCT  pMyStruct = new MY_STRUCT;

   void MyTestFunction()
   {
      delete pMyStruct;   // ok.
      delete LPMY_STRUCT; // Can not delete a type.
   }
