Rare android crash on SharedBuffer

cocos2d-x C++
1

Hi there,
I’m getting some rare crashes on android, can anyone tell me what can this be related??

I have 3 similar traces that appears to crash on SharedBuffer, the first two are from android 4.4 devices, the last is from android 6.0 devices.

Any info about what are these errors will be welcomed :slight_smile:

Thanks!!

Sorry, I forgot to say I’m using cocos2d-x 3.16

I was get above problem before.
In my case, I write many print() for get detail logs…
I tried many print() in for statement.
When I remove print() , above issue was disappear.
But it is only in my case.
Thanks

Thanks man!

However I’m not using print so error must be elsewhere :frowning:
