Bug ID: 241714
Summary: /usr/bin/diff --tabsize dies with SIGSEGV
Product: Base System
Version: 12.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: rlwestl...@gmail.com
On the three systems I've tried, /usr/bin/diff with --tabsize dies with
SIGSEGV, regardless of any other options or arguments.
I'm observing the crash on FreeBSD 12.1-RELEASE.
uname -a: FreeBSD coppermind 12.0-RELEASE-p10 FreeBSD 12.0-RELEASE-p10 GENERIC
amd64
freebsd-version -kur:
12.1-RELEASE
12.1-RELEASE
12.1-RELEASE
Outside of --tabsize, diff works normally.
The synopsis in diff(1) indicates that the option is a standalone. Later in the
man page it's shown as '-tabsize' (as opposed to --tabsize), and said to take
an argument (which makes sense); however I think the single dash is a typo
because when I run diff -tabsize 3 file1 file2, I get "diff: invalid option --
z".
I've also tested this on two 12.0-RELEASE-p10 systems (DO droplets), and seen
the crash on them as well. I updated the userland of those systems to
12.0-RELEASE-p11 and the same thing happened. The DO droplets are also amd64
machines with GENERIC kernel.
