--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Alternatively, we could reinterpret_cast<uintptr_t> before doing the
subtractions (and divide the result by sizeof(_Tp)), which would avoid the
overhead of adjusting the ASan tracking.
Either way, if my assumption about the cause is right, it's not a real bug in
std::vector, it's caused by incorrect (or insufficient) ASan instrumentation.
