      Description

      When hitting a breakpoint, we can right click on a C++ stack trace and do "Load QML Stack", which supposedly will decorate it with QML files and line numbers

      On Linux/gdb nothing happens.
      On Windows/cdb the debug logger says it crashed:

      To reproduce:
      Run the attached test-case, set a breakpoint in controller.h cppMethod().
      Clicking on the yellow background will call the C++ method, and cdb will break.
      Try "Load QML Stack"
