CCArray::removeAllObjects() crash much ?

cocos2d-x C++
#1 
SomeCCNode::~SomeCCNode()
{
    this->removeAllChildrenWithCleanup(true);
}

Same code is run smoothly on iOS, but crashes 9 out of 10 on android,
I followed in CCNode::removeAllChildrenWithCleanup, CCLog-ed some messages, found out :

m_pChildren->removeAllObjects()

is the one that crashes,

Is it not safe to explicitly invoke CCArray::removeAllObjects() or even CCNode::removeAllChildrenWithCleanup(bool)
