--- Comment #6 from Samuel Thibault <samuel.thiba...@ens-lyon.org> --- Well, yes and no: -Wrestrict does indeed warn about this in gcc 7 now, but -Wall -Wextra does not contain -Wrestrict, so that makes it almost useless. Is there a reason for not including -Wrestrict in at least -Wextra (I'd even argue for -Wall because it's really sure that there is a bug in code doing this)
