dim 19a08ec3f0 Fix a segfault in bsdgrep when parsing the invalid extended regexps "?" ... or "+" (these are invalid, because there is no preceding operand). When bsdgrep attempts to emulate GNU grep in discarding and ignoring the invalid ? or + operators, some later logic in tre_compile_fast() goes beyond the end of the buffer, leading to a crash. Fix this by bailing out, and reporting a bad pattern instead. Reported by: Steve Kargl MFC after: 1 week		2016-08-02 20:25:22 +00:00
