SYMPTOMS
When you compile a file, such as the following sample, with global optimization enabled, the following error occurs:
RESOLUTION
Remove the global optimizations for the source file or use the optimize pragma to remove the optimization for the function which is causing the error.
NOTE 1: If you are optimizing to minimize size (/O1) or maximize speed (/O2) then global optimization (/Og) is enabled as these options consist of several optimizations which includes global optimization.
NOTE 2: The default compiler options /GZ (Catch Release-Build Errors in Debug Build) and /ZI(Program Database for "Edit and Continue") are incompatible with /Og option.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Studio 97 Service Pack 3.
