glview->pollEvents(); randon crash mac on cocos2d-x 3.15.1

Hi,

I am updating a mac game from cocos2d-x 2.2.6 to cocos2d-x 3.15.1, the code update is done but I get a random crash con glview->pollEvents(); What can I do? I am using XCode 8.3.3 and Mac OS 10.12.15. Here is the backtrace from xcode:

HI again,

After days of debugging I could see that this line:

PoolManager::getInstance()->getCurrentPool()->clear();

from method void Director::mainLoop() was throwing the crash, commenting out this line and the crash goes away.

Thanks

Thanks for your feedback, but the crash stack seems not to be caused by PoolManager::getInstance()->getCurrentPool()->clear();.
I have no idea about how it crashed. Any reproduced demo could you provide?
