BUG: CXX0067: Error: Illegal Enum Value

• Microsoft CodeView for MS-DOS versions 4.0, 4.01, 4.1
• Microsoft CodeView for Windows versions 4.0, 4.01, 4.1
• Microsoft Visual Workbench for Windows, version 1.0

SYMPTOMS

When debugging a C++ program with CodeView version 4.1 or the Visual Workbench, the following error is generated when watching an enum type variable that is assigned a negative value:

   CXX0067: Error: Illegal Enum Value

RESOLUTION

A workaround when using the Visual Debugger or CodeView version 4.1 is to typecast the variable as an int in the Watch window. For example, if EnumData is an enum type variable with a negative value, set up the watch similar to the following:

   (int)EnumData

STATUS

Microsoft has confirmed this to be a problem in Microsoft CodeView for MS-DOS and Windows versions 4.0, 4.01, and 4.1, and in the Visual Workbench Debugger for Windows version 1.0.

This problem does not occur in CodeView version 4.25 for Win32s.

MORE INFORMATION

The following sample program demonstrates the problem. To reproduce the problem in CodeView for Windows or the Visual debugger, compile and link the sample as a QuickWin program or place the code in a Windows program.

This problem does not exist in a C program; it occurs only in C++ code.

Sample Code

/* Compile options needed: /Zi /Od
*/

void main(void)

  enum Days EnumData;
  EnumData = Monday;
