Yukihiro "Matz" Matsumoto 479af5c1bd mruby-regexp: bounds-check non-ASCII RE_CHAR in first_set_walk ...

The first-byte bitmap (bm[16]) is intentionally ASCII-only
(include/re_internal.h:75 documents it as 128 bits / ASCII), and
the matcher at re_exec.c:39 short-circuits for bytes >= 128. But
first_set_walk's RE_CHAR case wrote bm[a >> 3] without checking
a, overflowing the 16-byte stack buffer for any pattern
containing a byte >= 128.

When a >= 128, return FALSE so compute_first_set marks the filter
unusable, matching the bail-out pattern already used for RE_NCLASS
and RE_ANY. The pattern still compiles and matches; only the
first-byte optimization is skipped.

Reported by OSS-Fuzz (clusterfuzz testcase 4909069193510912).
