      attachments

      file name what
      test.qml code that creates crash! button
      gdb_with_log.txt gdb script (not portable)
      usage: 
      gdb --command=gdb_with_log.txt
      QQuickMenuPrivate_get called with pointer to destroyed QQuickMenu backtrace.txt QQuickMenuPrivate::get called with pointer to destroyed QQuickMenu backtrace (output of gdb bt command)
      this is not where crash happens, crash location is inconsistent (qt 6.9.0)
      log.txt gererated by gdb generalize_log /tmp/log.txt custom command (created by gdb_with_log.txt script) (qt 6.9.0)
