Bug in VC++ 2015 IDE when debugging?

Question

I am just observing an apparent error when debugging a C++ code in Visual Studio 2015 IDE. Is it a known problem?

When making steps (F10), the yellow arrow on the left that should point to the current place that is to be executed in the next step seems to be misplaced few lines upper. See the image

Notice the red value in the Locals panel that shows that the sqlStatement variable just changed. That means that the yellow arrow should actually be placed at the ret = SqlExecDirect(.... When following the debug steps in the source code carefully, I can see that indeed the current point is a bit farther than where the yellow arrow points.

The information about the VS--captured from the About dialog--follows:

I dare to answer my own question as it is unlikely that someone would found it without having the exact sources and the situation.

I use also Git as the VCS (installed from the official http://git-scm.com/). I also have set the Git core.autocrlf=false. It could be the case that I have touched the sources with another editor (Notepad++) or something...

When closing the solution, closing the Visual Studio, starting Visual Studio again, and opening the project, the Visual Studio warned about mixing line endings (CR LF). When the suggested fix was confirmed, the problem disappeared.

It makes sense if the code that sets the yellow arrow counts the lines differently than the rest of the editor (the editor window is more forgiving when the line endings are mixed).

As Visual Studio has its own Git support, the things could be confused during the cooperation of various software layers.
