As with many words, 'meaning' is multiply overloaded, and whichever concept (or concepts) come to mind is heavily dependent on the established or assumed context.
I would normally feel a sense of ambiguity when somebody wrote of "giving their life meaning" (but less so when spoken, because they might emphasise '_/meanin/_'), but would not feel much about the phrase "the meaning of life", nor "life, the universe, and everything!".
