constexpr doesn't imply anything like that.
constexpr variables can still be odr-used, their address taken, compared etc.

You are right, it seems to be the same issue except that my function is
constexpr, and I can't use `static constexpr ...` within the function, but
Barry mentioned that use case already.

You mentioned something that gcc needs to prove that this is safe, but I think
my use case is "safe" since it is constexpr :)

Looks like a dup of PR99091 to me.
