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++ 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:

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.

   delete LPMY_STRUCT; // Can not delete a type.
}
