                # args are not visible. If we do not do this, and the test in
                # question is throws_ok() with a regex, it will end up matching
                # against itself in the args to throws_ok().
                #
                # While it is possible (and maybe wise), to test if we are
                # indeed running under throws_ok (by crawling the stack right
                # up from here), the old behavior of Test::Exception was to
                # simply obliterate @DB::args altogether in _quiet_caller, so
                # we are just preserving the behavior to avoid surprises
                #
                my @frame_info = CORE::caller($height);
                @DB::args = ();
                return @frame_info;
            }
