FIX: C1001 Compiling File Containing Local Enum with Debug Info

ID: Q202584

The information in this article applies to:

Microsoft Visual C++, 32-bit Enterprise Edition, version 6.0

SYMPTOMS

When building a source file that contains a function with a local enumeration, and the compiler options are set to generate debug information, the compiler fails with the following error:

<filename>(line#) : fatal error C1001: INTERNAL COMPILER ERROR
    (compiler file 'msc1.cpp', line 1786)
    Please choose the Technical Support command on the Visual C++
    Help menu, or open the Technical Support help file for more information

This bug typically occurs only during a full build and not when compiling an individual file.

RESOLUTION

The following is a suggested workaround:

Turn off use of precompiled headers. This solution can result in excessive build times, especially for large projects.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

This bug was corrected in Visual Studio 6.0 Service Pack 3.
