I concur with Mark, with my 1400+ packages for workstations and servers, I have had zero issues. This seems like a pretty safe change. I just confirmed -fstack-protector is in my build logs although less frequently than I assumed for ports such as zenity, meld, pidgin (once or twice each). Other ports such as vlc mention it 2029 times. Not sure if the low counts are expected. _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
