I just tripped over something like this with grep v3.1-2 (Ubuntu 17.10
"artful"). the LC_ALL setting did not make a difference, and grep 3.1
passes the "test case" described in the bug description.
I have many text files, but one of them had a string of 49 \x00 chars. What
confused me was the s

Ah, thanks for pointing out. I understood it as the changes in grep 2.23
were deliberate, and during xenial this caused quite a lot of fallout
which we fixed.
Reverting the behavior for C makes sense. Thus now we still need to find
the actual fix in gnulib. Applying the doc and test to grep itself

While it is good to have the builders fixed, there is one worrying
aspect to this: this may happen to anything using grep and modifies the
output in an unexpected way while still returning a zero return code.
For example:
echo -e "Hello\nWörld" | LANG=C grep -v xxx; echo $?
will no longer return

The current version of grep was published on 2016-02-18 which could be around
when sbuild broke for me. Did not notice immediately as I was working on
something so I used the chroots directly (which works as there I have a UTF-8
setting there which sbuild deliberately drops).

Should add, when this first happened I asked someone else on the team to
check the package build. That was someone in the US, so there at least
would be no special keyboard setting, only the system language which
