1. Create a new project of type "Qt Quick Application - Empty".
2. Place a breakpoint in line 8 of main.cpp:

   QGuiApplication app(argc, argv);
   

3. Start the debugger.
   The breakpoint will be hit.
4. Check argv in the Locals view.
   The array contains to elements:

   argv	<2 Elemente>	char **
   	[0]	"D:\Testprojekte\build-untitled1008-Desktop-Debug\debug\untitled1008.exe"	char*
   	[1]	"-qmljsdebugger=port:56093,block,services:DebugMessages,QmlDebugger,V8Debugger,QmlInspector"	char*
   

5. Step forward.
6. Check argv in the Locals view again.
   Now the debugger claims that the array has only one element:

   argv	<ein Element>	char **
   	[0]	"D:\Testprojekte\build-untitled1008-Desktop-Debug\debug\untitled1008.exe"	char*
   

Looking at Creator's memory viewer, the array itself seems to not have changed, so I wouldn't expect the Locals view to change the display of argv.
