The latest release of SonarLint for Visual Studio adds secondary locations to help you better understand the issues it raises in your C++ code. SonarLint is a free static analysis extension installable from the Visual Studio Marketplace.

From the article:
All SonarLint issues specify a location in the code showing where the issue occurs. However, some of the more complex rules produce issues for which a single location is not enough to adequately explain why the issue has occurred. These more complex rules often identify additional locations in the code to help understand the problem. These additional locations are referred to as secondary locations.
