      Hello,

      I just rebuilt my desktop app on using the Qt 5.3 clang 64bit package. It crashes when the app exits when built on Mac OSX 10.9.3.

      The dump is shown below. It seems to crash in the QWindow::transientParent() function. This is not something I call directly and I did not see this with previous versions of Qt.

      Has anyone seen this and is there a work around?

      Many thanks,

      @

        Hi,

        What kind of application is it ? QWidget ? OpenGL ? QML ?

          Hello SGaist,

          It is a desktop app that has a QMainWindow with a QGraphics view that uses QGraphicsScene and OpenGL for drawing.

          I realize it could be just about anything but just thought I would ask if it is a common problem before I dive in and try to figure out the details.

          Thanks.

            I haven't encountered this problem yet. You should check the "bug report system":http://bugreports.qt-project.org to see if something known.
