-When extending regex buffers, make sure we allocate enough room for the
-state log. Merely doubling the space may not be enough if the current
-node has accepted a long run of characters. This part of the code only
-triggers with multibyte characters.
-
-Andreas.

- [BZ #15078]
- * posix/regexec.c (extend_buffers): Add parameter min_len.
- (check_matching): Pass minimum needed length.
- (clean_state_log_if_needed): Likewise.
- (get_subexp): Likewise.
- * posix/Makefile (tests): Add bug-regex34.
- (bug-regex34-ENV): Define.
- * posix/bug-regex34.c: New file.
