In the old --stdio interface the annotation is done just after one selects a symbol, while in --tui, now the default when the required libs are installed, we annotate all symbols with samples so that when annotation is asked we see what happened recently on that symbol. To achieve that the --stdio variant checks if the hist_entry being processed is the one selected by the user via the 's' hotkey. What happens now that we share the hist_entry abstractions with 'perf report' is that for minimizing locking contention multiple rb_trees are used, one for collecting the samples and other to browse/show them after resorting it by number of samples and decay them, which is done periodically. So the simple test in record_precise_ip doesn't work as we move hist_entries between those rb_trees. To fix it just check that the underlying struct symbol associated with those hist_entries is the same.
