--- Comment #3 from John Zwinck <jzwinck at gmail dot com> --- I'm aware of the workaround using __builtin_assume_aligned() - you can see I formulated an equivalent but pure C++ workaround using alignas() in the aforementioned Stack Overflow post. But 99% of users won't know to do that, so will pay a runtime cost for a C++ abstraction which is supposed to be free.
