What if some extra carefully written code detects some (non fatal) problem in
itself and decides to dump a decoded backtrace to some internal log buffer,
user will find this later and will send a bugreport to developers?
(yes, there are problems with simply doing dump_stack()).
Or perhaps we need dump_stack version that will print the dump into a
supplied buffer then?
