This issue affects processes which require tty input but are backgrounded. This issue has been discussed with kib@ and ed@ on freebsd-stable who confirmed the issue. Full details are in the thread titled "pty/tty or signal strangeness, or grep/bsdgrep bug?" here: http://lists.freebsd.org/pipermail/freebsd-stable/2012-October/thread.html#70204 This affects any process that requires tty input; it's not specific grep/bsdgrep. >How-To-Repeat: Step-by-step instructions are available: http://lists.freebsd.org/pipermail/freebsd-stable/2012-October/070204.html >Fix: kib@ did provide a patch but mentioned it would be best to wait for what ed@ proposes. >Release-Note: >Audit-Trail: >Unformatted:
