Re: grep-2.6.2 -Ff hangs on files with empty lines

I can trigger it with LANG='de_DE.utf8' but it doesn't happen with LC_ALL=C.
The blocking occurs in kwsearch.c (relevant commit: 
6d952beebdac1d8f31ba20abb12a756a9877e50d ), if I revert that specific 
patch the blocking is gone but now the output is incorrect, so this 
doesn't seem to seems to be source of the error.

$ src/grep -Ff <(printf '\na') <(printf 'a\nb')
a

$ LC_ALL=C src/grep -Ff <(printf '\na') <(printf 'a\nb')
a
b
