Digging into the bug, I suspect that the crashes happen when
m_childBeforeBoundary is a deallocated node, or a sibling of a deallocated
node. 

I believe that there are code paths that deallocate nodes without notifying the
range objects. 

One thing that caught my eye is that RangeBoundaryPoint::m_childBeforeBoundary
is a Node *, while m_containerNode is a RefPtr<Node>. Shouldn't
m_childBeforeBoundary be RefPtr<Node> too?
