关于Audio在IOS奔溃的问题-引擎组大大们请进

请问下目前用COCOS2D-X3.9的版本 在IOS上播放声音播放着过段时间会奔溃 想问下能不能直接升级到最新的

在void AudioEngine::uncache(const std::string &filePath) 我看见有这么一段注释 //@Note: For safely iterating elements from the audioID list, we need to copy the list
// since ‘AudioEngine::remove’ may be invoked in ‘_audioEngineImpl->stop’ synchronously.
// If this happens, it will break the iteration, and crash will appear on some devices.
