Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |missed-optimization Component|libstdc++ |c++ --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- I don't think there's anything wrong with std::any, Clang produces the same result when using std::any from libstdc++. So the difference is in the compiler, not the library implementation.
