FIX: C1001: Internal Compiler Error: msc2.cpp, Line 992

Q115323

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 source code that makes extensive use of pointers based on __self in conjunction with any of the /Ol, /Oe, or /Og compiler switches may cause the optimizing compiler to generate the following error message: fatal error C1001: internal compiler error (compiler file 'msc2.cpp', line 992) The problem only occurs when the compiler is invoked from the MS-DOS command line outside of Windows. The problem does not occur when the compiler is invoked from the command line inside a Windows MS-DOS session. RESOLUTION ========== To avoid the problem, do one of the following: - Upgrade to Visual C++ for Windows, version 1.5. This problem has been fixed with the version 8.0c compiler, supplied with Visual C++ for Windows, version 1.5. -or- - Do not use the /Ol, /Oe, or /Og optimizations. This can be accomplished at the module level by not specifying any of these switches and at the function level in the source code by using #pragma optimize directives to turn off the optimizations. To turn off the optimizations with a #pragma directive, place the following statement before the function containing the code that is causing the error: #pragma optimize ("leg", off) To turn the optimizations back on, place the following statement after the function: #pragma optimize ( "", on ) -or- - Use the fast compiler because the problem only occurs when the optimizing compiler is used. You can use the fast compiler by activating the /f compiler switch. -or- - Use the compiler from within Windows because the problem only occurs when the compiler is invoked from the MS-DOS prompt outside of Windows. STATUS ====== Microsoft has confirmed this to be a bug in the products listed above. This problem was corrected in Visual C++ for Windows, version 1.5.
