FIX: C1001 Compiling File Containing Local Enum with Debug Info (202584)

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.
