I see the problem. It's some issue in hist_browser__show_callchain.
--stdio doesn't show it because it doesn't seem to use that (?)

With this patch it shows percent for the first entry

@@ -791,7 +791,7 @@ static int hist_browser__show_entry(struct hist_browser *browser,
                };
 
                printed += hist_browser__show_callchain(browser,
-                                       &entry->sorted_chain, 1, row, total,
+                                       &entry->sorted_chain, 2, row, total,
                                        hist_browser__show_callchain_entry, &arg,
                                        hist_browser__check_output_full);

But the numbers are still different from what --stdio outputs,
so there are some deeper issues.

I doubt I caused this, probably some latent bug that just got triggered.

Namhyung?
