Subject: dfa: fix sigsegv on multibyte character classes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reported by Jaroslav Škarvada <jskarvad@redhat.com>.  This is
unfortunate.  grep needs an automatic testcase generator.

* NEWS: Document bug.
* THANKS: Mention reporter.
* src/dfa.c (set_bit_casefold): Change type of first argument for
self-documentation.
(parse_bracket_exp): Fix call.
* tests/Makefile.am: Add new testcase.
* tests/char-class-multibyte: New testcase.
