Why did you use HelloWorldLayer like this?

#ifdef __cplusplus
8   
extern "C" {
9   
#endif
10  
    JNIEXPORT void JNICALL Java_com_demo_jniCCLabelTTF_nativeCall(JNIEnv *env, jobject thiz, jstring msg)
11  
    {
12  
        CCLog("nativeCall");
13  
        std::string str;
14  
        char* cMsg = strdup((*env).GetStringUTFChars(msg, 0));
15  
        HelloWorld hello;   // You allocated HelloworldLayer on stack. No crashes will be strange.  -_-!!!
16  
        hello.changString(cMsg);
17  

18  
        env->ReleaseStringUTFChars(msg, cMsg);
19  
        free(cMsg);
20  
    }
21  
#ifdef __cplusplus
22  
}
23  
#endif
