Hi, thank you so much for your help.

>From example, most(probably all) of them use #popRemappableOop and
#pushRemappableOop in a single method(function). 

        "remap methodContext in case GC happens during allocation"
        self pushRemappableOop: methodContext.
        newContext := self instantiateContext: (self splObj:
ClassBlockContext) sizeInBytes: contextSize.
        methodContext := self popRemappableOop. 

Is it possible to use them in two function? i.e. one push and the other pop. 

Is it possible that other method pop the object that I just pushed? It
sounds impossible if every method, do their push and pop before return. But
while I'm debugging, I actually saw my object on remappableOop being remove,

What change objects on remappable-stack?
