 	- _rl_copy_to_kill_ring: don't assume that rl_kill_ring has been
 	  allocated if _rl_last_command_was_kill is non-zero; make sure it's
 	  non-null before indexing into it

+variables.c
+	- set_pwd: only believe $PWD if it begins with a slash; try to canonicalize

+	- do_compound_assignment: make sure to dispose of word list generated by
+	  expand_compound_array_assignment; fixes memory leak reported in

+
+variables.c
+	- adjust_shell_level: clamp the value of shell_level at 1000 and reset
+	  there, instead of > 1000, since the itos replacement code doesn't
+	  handle the value 1000.  Fixes bug reported by ziyunfei <446240525@qq.com>

+shell.h,parse.y
+	- save_parser_state,restore_parser_state: now save and restore redir_stack,
+	  short-circuiting if need_here_doc == 0.  If we save a non-zero value for
+	  need_here_doc, we have to make sure there is something valid for
+	  gather_here_documents to work on.  Fixes bug reported by

+array.c
+	- array_to_assign: use ansic_shouldquote to check whether each element
+	  value contains non-printable characters and use ansic_quote to
+	  generate the value instead of using sh_double_quote unconditionally
+
+assoc.c
+	- assoc_to_assign: if either the key or the value of an associative array
+	  element contains non-printable characters (ansic_shouldquote returns
+	  true), use ansic_quote to quote them instead of using double quotes
+	  unconditionally

+subst.c

+
+builtins/evalstring.c
+	- parse_string: if we get a longjmp to top_level with DISCARD as the
+	  code (in which case we are going to go on), return -DISCARD to our
+	  caller (always xparse_dolparen) after doing our own cleanup instead
+	  of calling jump_to_top_level
+
+parse.y
+	- xparse_dolparen: if parse_string returns < 0, do the appropriate
+	  cleanup and then jump_to_top_level with the negative of the return
+	  value.  This allows us to do the appropriate parser cleanup in
+	  case we're not going to exit the shell.  Fixes bug reported by Brian
+	  Carpenter <brian.carpenter@gmail.com>
+
+subst.c
+	- extract_delimited_string: if a recursive call to one of the extract_
+	  functions or a call to ADVANCE_CHAR leaves i past the end of the
+	  string, cut the loop off at the end of the string.  Fixes bug
+	  reported by Brian Carpenter <brian.carpenter@gmail.com>
