+ * cli/cli-script.c (copy_command_lines): New function.
+ * defs.h (copy_command_lines): Export.
+ * testsuite/gdb.base/commands.exp: New tests for commands
+ attached to a temporary breakpoint, and for commands that
+ delete the breakpoint they are attached to.
+

+
+ * breakpoint.c (bpstat_stop_status): Instead of copying the
+ pointer to the breakpoint commands struct, make a new copy
+ of the struct and point to that.
+ (bpstat_clear): Free the commands struct.
+ (bpstat_clear_actions): Free the commands struct.
+ (bpstat_do_actions): Free the command actions. Also execute
+ the local cleanups, instead of deleting them.
+ (delete_breakpoint): Leave the commands field of the bpstat
+ chain alone -- it will be freed later.
