cocos2dx in qt weird crash problem



  • I'm combining cocos2d-x 3.12 with Qt 5.7 and now I am able to render a cocos2d::Scene with a image as cocos2d::Sprite in a QMainWindow.

    But, the problem is, if I just leave the app as it is ( do not move the mouse), it will just be fine, once I move my mouse over the app window, the app will crash with a error message:

    The program has unexpectedly finished.
    QtCocos2dx.app/Contents/MacOS/QtCocos2dx crashed.
    

    Sometimes there will be a error message like :

    objc[72738]: autorelease pool page 0x7fbd4c96e000 corrupted
      magic     0x00000000 0x00000000 0x00000000 0x00000000
      should be 0xa1a1a1a1 0x4f545541 0x454c4552 0x21455341
      pthread   0x0
      should be 0x7fff7c7fc000
    

    BTW, some information might be useful from cocos2d-x log output at initial stage:

    {
    	gl.supports_vertex_array_object: true
    	cocos2d.x.version: cocos2d-x-3.12
    	gl.vendor: Intel Inc.

    	gl.renderer: Intel HD Graphics 5000 OpenGL Engine
    	cocos2d.x.compiled_with_profiler: false
    	cocos2d.x.build_type: DEBUG
    	cocos2d.x.compiled_with_gl_state_cache: true

    	gl.supports_ETC1: false
    	gl.supports_BGRA8888: false

    	gl.supports_S3TC: true
    	gl.supports_OES_depth24: false
    }
    

    And I tried to debug and getting the following informations:

    1  (anonymous namespace)::AutoreleasePoolPage::pop(void *)                                 0x7fff9426ae71

    4  -[NSApplication run]                                                                    0x7fff90ededfb

    8  main                                                                        main.cpp 18 0x100006ae0    
    9  start                                                                                   0x7fff91ada5ad 
    10 start                                                                                   0x7fff91ada5ad 
    
    

    Any suggestion will be appreciated, thanks :)
