Also free the tree using free_tree for "<re>{0}", and lower OP_DUP_QUESTION to OP_ALT: "a?" is equivalent to "a|". Adjust invocation of mark_opt_subexp. (parse_sub_exp): Create a single SUBEXP node. * posix/regex_internal.c (re_dfa_add_node): Remove last parameter, always perform as if it was 1. Do not initialize OPT_SUBEXP and DUPLICATED, and initialize the DFA fields representing the transitions. * posix/regex_internal.h (re_dfa_add_node): Adjust prototype. (re_token_type_t): Move OP_DUP_PLUS and OP_DUP_QUESTION to the tokens section. Add a tree-only code SUBEXP. Remove OP_DELETED_SUBEXP. (bin_tree_t): Include a full re_token_t for TOKEN. Turn FIRST and NEXT into pointers to trees. Remove ECLOSURE. 2004-12-28 Paolo Bonzini <bonzini@gnu.org > [BZ #605] * posix/regcomp.c (parse_bracket_exp): Do not modify DFA nodes that were already created. * posix/regex_internal.c (re_dfa_add_node): Set accept_mb field in the token if needed. (create_ci_newstate, create_cd_newstate): Set accept_mb field from the tokens' field. * posix/regex_internal.h (re_token_t): Add accept_mb field. (ACCEPT_MB_NODE): Removed. * posix/regexec.c (proceed_next_node, transit_states_mb, build_sifted_states, check_arrival_add_next_nodes): Use accept_mb instead of ACCEPT_MB_NODE.
