Hello people!

Updated to latest cocos2d (cocos2d v2.1-beta3), I'm having a EXC_BAD_ACCESS error caused by [CCDirector showStats] method, but it only happens sometimes. Is somebody having the same problem? If I disable the stats, the game runs perfectly. Also note that I'm using cocos2d as an static library and ARC.

Screenshots:

Thanks in advance!

@Dani:
Does it happen when you start a new project from the template ? If so, which template are you using ? thanks.

@riq: No, it only happens on my project. But this didn't happen before when using cocos2d v2.1-beta1. And it only happens sometimes, just after replacing scenes. Do the stats use some assumption or condition we should know? Anyway, if this doesn't happen to other people, don't bother. I will just disable the stats.

Oh, by the way, my project template is based on the most simple cocos2d v2.1-beta3 template, with no physics. I have just created a new cocos2d project and added my game stuff. All working properly with the stats disabled.

Another thing, I would like to know when are the stats added to the scene, before or after the init method of my main class layer?

Thanks!

@Dani:
The stats are initialized with the director, and are drawn after all the elements of the scene were drawn.
Are you "ending" the director ?
Try enabling the NSZombies also

@riq: No, I'm not terminating the director at any point. And NSZombies don't report any problem. It's a very obscure behavior, I've been spending hours trying to figure out what's going on.

Very strange. Could you create a ticket with the code to reproduce it ? Thanks.

@riq: man, I have started a new project and this error occurs just when using the HKTMXTiledMap class, so I suppose there must be some changes in the new cocos2d 2.1-beta3 classes that are affecting the HKTMXTiledMap class behavior.

@Dani:
Yes. I don't know why HKTMXTileMap and cocos2d v2.1-beta3 are crashing. It could be due a bug fix in cocos2d, or a new bug introduced in v2.1-beta3, or something else. But in order to fix it/understand why it is crashing I will need more info.

https://github.com/richardgroves/HKTMXTiledMap-crash.git is a project that will repro the crash 100%

Everything looks fine on the HKTMXTiledMap side. I saw nothing out of the ordinary.

The ShowStats stuff is new to me (as I still run cocos2d 1.1)

I found setting #define CC_TEXTURE_ATLAS_USE_VAO 0 (instead of 1 which it is by default) "fixes the problem"
