ID: Q115855

1.00 WINDOWS kbtool kbfixlist kbbuglist

The information in this article applies to:

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

    - Microsoft Visual C++ for Windows, version 1.0

SYMPTOMS

Compiling code using the /Ol, /Oe, /Og, or /Ox compiler options may generate the following internal compiler error, but only when the compiler is run from MS-DOS, not from an MS-DOS prompt in Windows:

   fatal error C1001: internal compiler error (compiler file
                      'msc2.cpp', line 992)

RESOLUTION

To work around this problem, you can do one of three things:

1. Disable optimization by removing the /Ox, /Ol, /Oe, or /Og options.

   -or-

2. Use the fast compiler option /f.

   -or-

3. Upgrade to Visual C++ for Windows version 1.5. The C/C++ compiler

   version 8.0c does not display this behavior.

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.
