--- Comment #1 from Aaron Greig <aaron.greig at codeplay dot com> --- actually it seems that vector_size(16) creates a type that is over aligned, the following assert fails: static_assert(std::alignment_of<int4>::value <= alignof(max_align_t), "over aligned!"); so I think I should have been using a custom allocator in the std::vector? It might be worth considering generating a warning for such cases
