cocos2dx4.0闪退 cocos2d::Label::updateBuffer

Cocos2d-x

此bug特征，平均闪退时间在玩游戏1小时后，玩家每天闪退3次以上,我实在是解决不了这个问题
bugly抓到的堆栈如下：

玩久了闪退，很大原因在内存泄漏，可以检查看看是否有内存泄漏

#3

根据堆栈调用，大致猜一下。看看哪个节点是ScrollView下挂着TextureAtlas的，应该是这个有问题

#4

确实有内存泄漏，但是太多了，我不敢动它

#5

确实，极有可能，我这就去排查

#6

为啥这些问题，都是android的呢，iOS确很少呢？我的项目之前也遇到过这样的问题，所以我建议你检查你接入的SDK的回调执行时机，是不是一定是在openGL状态就绪后，再执行回调，因为java端调用runOnGLThread，并不能保证安全。

#7

的确发现了安卓java回调lua的时候有点问题,已经修改了，等测试一段时间再看看

#8

没用，java调用c++已经确定安全了，游戏内甚至没有使用TextureAtlas的地方了，依然在这个地方闪退

#9

怎么确定是调用安全了呢，可以给一下你们的调用过程吗？

#10

label里面用到了TextureAtlas。当然，这样的话，问题的范围就更大了，更不好确定了

#11

而且，刚好，label继承自ProtectNode，拥有void Label::updateBuffer(TextureAtlas* textureAtlas, CustomCommand& customCommand)接口和void Label::updateEffectUniforms(BatchCommand &batch, TextureAtlas* textureAtlas, Renderer *renderer, const Mat4 &transform)接口，似乎很符合你这里显示的报错信息
