FIX: C1001: reg86.c, line 4479, 4600

ID: Q114076

7.00 | 1.00 MS-DOS | WINDOWS kbtool kbfixlist kbbuglist

The information in this article applies to:

The Microsoft C/C++ Compiler (CL.EXE), included with:

    - Microsoft C/C++ for MS-DOS, version 7.0
    - Microsoft Visual C++ for Windows, versions 1.0

SYMPTOMS

The compiler generates the following internal compiler error message when the sample program below is compiled. The C/C++ 7.0 compiler generates:

   fatal error C1001: INTERNAL COMPILER ERROR
      (compiler file '@(#)reg86.c:1.26', line 4479)

The C/C++ 8.0 compiler generates:

   fatal error C1001: internal compiler error
      (compiler file '@(#)reg86.c:1.26', line 4600)

The internal compiler error occurs when using the optimizing compiler regardless of optimizations being used.

RESOLUTION

To avoid the error, use the fast compiler instead of the optimizing compiler. Use of the fast compiler can be forced by using the /f compiler switch. Note that you can still use optimizations even though you are using the fast compiler.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed above. This problem was corrected in Visual C++ version 1.5.

Sample Code

/* Compile options needed: /c /f-
*/

typedef struct sname1

    {
    long lField11;
    long lField12;
    long lField13;
    long lField14;
    long lField15;
    } Table1;

typedef struct sname2

    {
    long lField21;
    long lField22;
    long lField23;
    long lField24;
    long lField25;
    char cField26;
    } Table2;

void func1(long);
int func2(int *, Table1 *);
void func(int lParam1, Table2 * ptabParam2);

Table1 LevelLists[4];

void func(int lParam1, Table2 * ptabParam2)

{

    {
        func1(ptabParam2->lField25 - 8L);
    }
    lParam1= func2(&lParam1, &LevelLists[((ptabParam2->cField26)&3)]);

}
