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.
