Update. 2003-11-19 Jakub Jelinek <jakub@redhat.com> * posix/regexec.c (extend_buffers): Don't allocate twice as big state_log as needed. Don't modify pstr->valid_len for mb_cur_max == 1 !icase !trans. * posix/regcomp.c (free_bin_tree): Removed. (create_tree): Add dfa argument. Don't call re_malloc for each tree, instead allocate from str_tree_storage. (re_dfa_add_tree_node): New function. (free_dfa_content): Handle freeing if dfa->nodes == NULL or dfa->state_table == NULL. (re_compile_internal): Call free_dfa_content if init_dfa fails. Call free_workarea_compile, re_string_destruct and free_dfa_content for most of the other failure paths. (init_dfa): Initialize str_tree_storage_idx. Don't clear any fields on allocation failure. (free_workarea_compile): Free str_tree_storage chunks instead of free_bin_tree (dfa->str_tree). (parse): Call re_dfa_add_tree_node instead of re_dfa_add_node followed by create_tree. Add dfa argument to remaining create_tree calls. Remove new_idx variable. Remove calls to free_bin_tree. (parse_reg_exp, parse_branch, parse_expression, parse_sub_exp, parse_dup_op, parse_bracket_exp, build_charclass_op): Likewise. (duplicate_tree): Remove calls to free_bin_tree, add dfa argument to create_tree. * posix/regex_internal.h (BIN_TREE_STORAGE_SIZE): Define. (bin_tree_storage_t): New type. (re_dfa_t): Add str_tree_storage and str_tree_storage_idx fields. * posix/Makefile (tests): Add bug-regex21. (generated): Add bug-regex21-mem, bug-regex21.mtrace, tst-rxspencer-mem and tst-rxspencer.mtrace. (tests): Depend on $(objpfx)bug-regex21-mem and $(objpfx)tst-rxspencer-mem. (bug-regex21-ENV, tst-rxspencer-ENV): Set. ($(objpfx)bug-regex21-mem, $(objpfx)tst-rxspencer-mem): New. * posix/tst-rxspencer.c (main): Add call to mtrace. Free line at the end. * posix/bug-regex21.c: New test. * posix/regexec.c (get_subexp): After calling get_subexp_sub
