Crash in ScriptingCore::cleanup() on termination (iOS)

[pandemosth]

I'm getting an EXC_BAD_ACCESS when the iOS app is terminated.

Offending line is 711 of ScriptingCore.cpp:

for (auto iter = _js_global_type_map.begin(); iter != _js_global_type_map.end(); ++iter)
{
    free(iter->second->jsclass);  /* Crashes here */
    free(iter->second);
}

This is happening in my own project and also js-tests and js-moonwarriors samples. To reproduce run the app from XCode then double tap home key and kill the app.

Hi Comm1x i am getting the same error.. Any clue how to resolve this

[pandamicro]

This is a known issue, but it's not a priority currently, because when user terminate the app on iOS, the crash doesn't have very bad effect

[siddhanth]

Hi, @pandamicro i am also seeing a crash cocos2d::SpriteFrame::getTexture() is it also because of the same issue ? Or this would be seperate..detailed ticket is present here [1]

@pandamicro user device will send crash report to apple server, it will count in apple connect. Please fix it

[mehnis3050]

is there a fix for this issue. I have a lot of issues reported on iTunes connect which is increasing my crash to session ratio.. there has to be a fix. it hampers identifying the actual crashes.

[gitcalculus]

lot of crash report! Please fix it! @pandamicro

The issue is not relative to cocos2d-js and should be fixed in cocos2d-x. cocos2d-x issue here https://github.com/cocos2d/cocos2d-x/issues/14092
