cocos2dx js crash in GC

Hi, guys, I want to know, in which case will make js GC crash?

var jsVar = new CocosNode();

if node is not exist, called cc.sys.garbageCollect, will this make a GC crash?

Or not set armature setCompleteCallback null will make a GC crash?

I called cc.sys.garbageCollect in update function every 0.5s, it will crash more frequently. I have set gc callback, so I can see it crashed in js GC

JS_SetGCCallback(_rt, &gcCallBack, NULL);

Hope anyone can help, thanks

I got the same issue.
Have you resolved that?
