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 specificpatch the blocking is gone but now the output is incorrect, so thisdoesn'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
