Bug 574662 – sys-apps/grep-2.23: -z option breaks character ranges

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ulrich Müller 2016-02-13 22:53:45 UTC]

According to the documentation, option -z or --null-data should cause grep to treat newlines as ordinary data. Therefore, in the following example the regexp ^[1-4]$ should _not_ match the input data:

$ printf '12\n34\0' | LC_ALL=en_US.utf8 grep -z -e '^[1-4]*$' | od -t x1
0000000 31 32 0a 33 34 00
0000006

Spelling it out as [1234] makes it work as expected:

$ printf '12\n34\0' | LC_ALL=en_US.utf8 grep -z -e '^[1234]*$' | od -t x1
0000000

It is also locale dependent, I see the problem with LC_ALL=en_US.utf8 and LC_ALL=en_US, but not with LC_ALL=C.

sys-apps/grep-2.24 fixes the problem for me.
Can this bug be closed?
