    Description

      QJSEngine.evaluate crashes when called from a signal emitted by another thread.
      The following message about isolate.h is written to the console:

      #

      1. Fatal error in q:\qt5_workdir\w\s\qtjsbackend\src\3rdparty\v8\src\isolate.h, line 446
      2. CHECK(isolate != 0) failed
