# Which template did you use? cocos2dx only, or cocos2dx_chipmunk, cocos2dx_box2d, cocos2dx_lua?
# I use 0.9.1 xcode4 temple + xcode v4.1 Build 4B110 + OS X 10.7, cannot reproduce your problem. After I read the attached rtf file, I can not get enough infos to locate the crash. Could you please add
#define COCOS2D_DEBUG 2
into the start of YourGame/libs/cocos2dx/platform/CCPlatformMarcos.h, then paste the error log here?
