CCDictMaker xmlSAXUserParseMemory crash on ios


hello I’m trying to use this method to parse an plist file instead of ios sdk. The application crashes.
I look with the debugger and I see that this line is where the application crashes

bool CCSAXParser::parse(const char pszFile) {

//Here the application crashes
Ln 65: int result = xmlSAXUserParseMemory;

the method return value is 4?? but,when i change the file’ end name to
.xml ,it return 0 right? isn’t it! Hava some body found this issue.

I use cocos2d-x 2.0.3 on mac 10.8.1 and xcode 4.5.1.
