https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251081 Bug ID: 251081 Summary: Grep Crashes with both «--after-context» «--max-count» Switches are Used Product: Base System Version: 12.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: CrazyMihey@Ya.Ru Created attachment 219606 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=219606&action=edit Grep Memory Dump 12.2 x64 FreeBSD Grep Utility Crushes in a case of simultaneously specifying two Switches: «--after-context=NUM» (-A NUM) and «--max-count=NUM» (-m NUM). This happens when Russian Language (for Example) is Used. The Example to ReProduce this Error (EveryOne can Try, if Brave enough): # id -c russian #grep --after-context="10" --max-count="2" "" "/etc/passwd" # $FreeBSD: releng/12.2/etc/master.passwd 359447 2020-03-30 17:07:05Z brooks $ # Segmentation fault (стек памяти сброшен на диск) or, without specifying the «Russian» LogIn Class (ReProduced on any System): # env LANG="ru_RU.UTF-8" grep --after-context="10" --max-count="2" "" "/etc/passwd" || printf "Error Number: %u (0x%.2X).\n" "${?}" "${?}" # $FreeBSD: releng/12.2/etc/master.passwd 359447 2020-03-30 17:07:05Z brooks $ # Segmentation fault (стек памяти сброшен на диск) Error Number: 139 (0x8B). # Looks like 0x80 + 0x0B: «SIGSEGV». shows the same Result. «egrep» does the same. # grep --version grep (GNU grep) 2.5.1-FreeBSD This Issue was found with these Systems: ● FreeBSD 11.2-RELEASE #0 r335510: Fri Jun 22 04:32:14 UTC 2018 GENERIC amd64 ● FreeBSD 12.1-RELEASE-p2 r358570 CrazyBook i386 ● FreeBSD 12.2-RELEASE r366954 GENERIC i386 ● FreeBSD 12.2-RELEASE r366954 GENERIC amd64 This is not a Critical Error, but IMHO, Developers should Know about It.
