1. Open the OpenGLWindow example from Qt's repository.
   It's in qtbase\examples\gui\openglwindow\openglwindow.pro
2. Open main.cpp.
3. Go to the line:

   glVertexAttribPointer(m_posAttr, 2, GL_FLOAT, GL_FALSE, 0, vertices);
   

   It should be around line 165.

4. Right-click on "GL_FALSE" and select "Find Usages" from the context menu.
   In the search results, there will be the line

   /*      GL_COLOR_BUFFER_BIT */
   

   from C:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\um\gl\GL.h (or similar).

5. Double-click this search result.
   GL.h will open at the line

   #define GL_FALSE                          0
   

The line is found correctly but the wrong line is displayed in the search results. They should display the actual line.
