Can't expand array of QProcesses in Locals and Expressions

1. Build the following code with MinGW:

           const int N = 14;
           QProcess proc[N];
           for (int i = 0; i != N; ++i) {
               proc[i].start("sleep 10");
               proc[i].waitForStarted();
           }
   

   (Taken from function void testQProcess() in tests\manual\debugger\simple\simple_test_app.cpp:4210.)

2. Stop at a breakpoint behind it with gdb.
3. Look at the value displayed for proc in Locals and Expressions view:

   		N	14	int
   		proc	@0x28fd90	QProcess [14]
   

   proc can't be expanded to show the single QProcesses inside the array.

It should be possible to expand the array and show the single items. When using MSVC2013 and cdb or for an array of more trivial types, this works correctly.
