Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|target |libstdc++ --- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> --- I think this is at most a C++ std library QOI issue - IIRC you have to use a different allocator for types requiring bigger alignment than any of the standard types. That is simply using std::vector<T> for such types doesn't guarantee proper alignment as memory is obtained via std::new.
