There is an easy solution, use canonical with one and only one version of the URL.
In this case, if any search engine would treat these URL differently, canonical would solve that issue.
I personally would not rely on the fact that all search engines would necessarily consider such URLs as identical, even if they probably should.
Take the safe road, go for canonical. I would for sure. It is very easy to implement.
