Jiang An <de34 at live dot cn> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |de34 at live dot cn --- Comment #8 from Jiang An <de34 at live dot cn> --- (In reply to Pavel Novikov from comment #7) > Now it's time to file a bug in MSVC's standard library. This was by design. MSVC STL intendedly only enabled changes in P0608R3 since C++20 (https://github.com/microsoft/STL/pull/1629#issuecomment-778895630). But given the author of P0608R3 applied the changes to libc++ in C++17 mode, I think it makes more sense to treat it as a DR. I've opened this issue: https://github.com/microsoft/STL/issues/4412
