This applies to ALL versions of FreeBSD (tested/verified on 2.2.8 and all 4.x revisions). This bug more than likely applies to OpenBSD and NetBSD as well. I'm hoping this bug can get squashed before 4.4-STABLE comes out... >How-To-Repeat: $ printf "1\n2\n3\n" | sed '1,2H;2G' The output is: 1 2 1 2 3 But should be: 1 2 (blank line) 1 2 3 >Fix: Approximately line 151 of src/usr.bin/sed/process.c: cspace(&PS, hs, hsl, 0); Change to: cspace(&PS, "\n", 1, 0); cspace(&PS, hs, hsl, 0); >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
