 ## Syntax
 
-```cpp
-/Zo[-]
-```
+> **`/Zo`**\[**`-`**]
 
 ## Remarks
 
-The **/Zo** compiler switch generates enhanced debugging information for optimized code. Optimization may use registers for local variables, reorder code, vectorize loops, and inline function calls. These optimizations can obscure the relationship between the source code and the compiled object code. The **/Zo** switch tells the compiler to generate additional debugging information for local variables and inlined functions. Use it to see variables in the **Autos**, **Locals**, and **Watch** windows when you step through optimized code in the Visual Studio debugger. It also enables stack traces to show inlined functions in the WinDBG debugger. Debug builds that have disabled optimizations ([/Od](od-disable-debug.md)) do not need the additional debugging information generated when **/Zo** is specified. Use the **/Zo** switch to debug Release configurations with optimization turned on. For more information on optimization switches, see [/O Options (Optimize Code)](o-options-optimize-code.md). The **/Zo** option is enabled by default in Visual Studio when you specify debugging information with **/Zi** or **/Z7**. Specify **/Zo-** to explicitly disable this compiler option.

-The Code Analysis tool reports this warning when there is an internal error with plugin dependencies, not in the code being analyzed.
+The Code Analysis tool reports this warning when there's an internal error in the plugin dependencies. It's not caused by an issue in the code being analyzed.
+
+In some cases, it's possible to work around this issue by disabling the **Enable Code Analysis on Build** property. To disable this build property, open the Property pages dialog for your project. In the **Solution Explorer** window, right-click on the project (not the solution) and select **Properties** in the shortcut menu. Set the **Configuration** to **All Configurations** and the **Platform** to **All Platforms**. Open the **Configuration Properties** > **Code Analysis** > **General** property page. Modify the **Enable Code Analysis on Build** property to **No**. Choose **OK** to save your changes, and then save your project files. Rebuild your project to verify that the issue no longer occurs.
+
+If the issue continues, you can report it to Microsoft. For more information on how to report an issue, see [How to report a problem with the Visual C++ toolset or documentation](../overview/how-to-report-a-problem-with-the-visual-cpp-toolset.md).
