Hi, this bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69681 still appears to be UNCONFIRMED, and I'm really interested whether this is actually a GCC bug or a valid behavior based on the C++ standard. Note that clang has no problem treating the comparison of global addresses as constexpr, so I've switched to using Clang while this bug isn't fixed on GCC, since I really need this behavior. However, if this is not considered to be a bug by the GCC developers and they will never fix it, I'll try not to rely on it since I don't want to lose compatibility with GCC forever. Here's a link if you'd like to play with this on an online compiler: https://godbolt.org/g/upGHrl Thanks!
