1. Build the following code with MSVC2013:

           QString str = "Hello ";
           str += " big, ";
           str += "\t";
           str += "\r";
           str += "\n";
           str += QLatin1Char(0);
           str += QLatin1Char(1);
           str += " fat ";
           str += " World";
           str.prepend("Prefix: ");
   

   (Taken from function void testQString1() in tests\manual\debugger\simple\simple_test_app.cpp:3980.)

2. Step through it with cdb.
3. Look at the value displayed for str in Locals and Expressions view.
   You'll never see the " fat World" part. The displayed value ends at the 0.

Creator should show the whole string. When compiling with MinGW and using gdb, this works correctly.
