Bug 5119: Null pointer dereference in makeMemNodeDataOffset() (#1623)

    UndefinedBehaviorSanitizer: undefined-behavior mem_node.cc:27:26 in
    runtime error: member access within null pointer of type 'mem_node'

Since only the address of the data member is computed, a compiler is
likely to perform pointer arithmetic rather than dereference a nullptr,
but it is best to replace this UB with a safe and clearer alternative.
