One aside -- parsing text from the debugger is never stable, not with gdb, not with lldb. A long time ago IDEs used to use the debugger and try to parse the output ("annotated mode" in gdb would be an early example of trying to make it more machine parseable for emacs). MI ("machine interface") was designed exactly for this reason -- so an IDE would have a stable protocol to use when communicating with the debugger.
Neither gdb nor lldb changes its output frequently -- but it does change over time. Any debugger scripting based on regexp-matching the output from these debuggers will break on occasion and will require maintenance.
