regex: fix heap-use-after-free error
[BZ #18040] Problem reported by Saito Takaaki <tails.saito@gmail.com> in https://debbugs.gnu.org/32592 Call stack get_subexp->get_subexp_sub->clean_state_log_if_needed may call extend_buffers which reallocates the re_string_t internal buffer. Local variable 'buf' was not updated in such case, resulting in use-after-free. * posix/regexec.c (get_subexp): Update 'buf' after call to get_subexp_sub.
