--- Comment #2 from Sam James <sjames at gcc dot gnu.org> ---
> However, formally speaking this triggers undefined behaviour as the memcpy's
> source and destination areas overlap. (Although the C standard does
> distinguish between inexact and exact overlap in assignments, there's no such
> distinction for library routines like memcpy.)
