When running sbuild (or now the buildd, too), the build breaks when trying to compile a generated file. I traced the problem down to grep suddenly acting weird. When not having any language set (or a non-UTF8 mode) it will start printing some lines of a source file and then suddenly end that by printing "Binary file ... matches". With the attached file, the difference can be observed (running Xenial): LANG=C grep -v xxx grant_table.h and LANG=C.UTF-8 grep -v xxx grant_table.h - Upstream bug: http://bugs.gnu.org/23234 + SRU INFORMATION + =============== + Upstream fixes: + - http://git.savannah.gnu.org/cgit/grep.git/commit/?id=d8a366218 (but depends on previous patches and is not sufficient by itself) + - http://git.savannah.gnu.org/cgit/grep.git/commit/?id=d8a366218 (tests+doc) + + Test case: + + Call grep on a file or a string with non-ASCII characters in the C locale: + $ echo 'héll☺ ≥x' | LC_ALL=C grep . + In xenial this just shows "Binary file (standard input) matches", with the fix it should show the actual input string (with some garbled output of course as the UTF-8 chars cannot be displayed in C) + + Regression potential: grep is being used in tons of places; during + xenial we had to fix/put a "use grep -a" workaround into a lot of + packages to fix the fallout from grep 2.23 which introduced this.
