What does the stack trace mean?

cocos2d-x C++
#1

My game was crashing at some point when running on android. I was able to get the stack trace, but cant seem to understand anything from it.

StackTrace

I have seen line CCObject.cpp:92 which reads thus
@ CCAssert(m_uReference > 0, “reference count should greater than 0”);@
What does this mean? What am I doing wrong?

#2

I was getting the same assert error when the CCDictionary I was trying to load from a plist file had a close tag missing and was failing to load.
It was working in android and win32 but not iOS.

Can you debug it?

#3

This error means that you are trying to retain an object that has already been released.
Its quite hard to guess the error without seeing any code.

It might be possible that you have released the object you are trying to add before or it is an autorelease object which never gets retained and therefore is automatically deleted by CCAutoreleasePool.
