      Hi,

      When running the attached test "bug.cpp" I'm getting a SIGSEGV crash.
      After debugging I've found that the "QCoreApplication::sendSpontaneousEvent(q, &e)" call in the file "qtbase/src/widgets/kernel/qwidget.cpp:5112" affects in the "paintEngine" Object in such a way that the ">d_func()>currentClipDevice" is no more accessible.Please check the "before.png" and the "after.png" screenshots.

      regards
      Haithem.
