From: Namhyung Kim <namhyung....@lge.com>
The commit 2b8bfa6bb8a7 ("perf tools: Centralize default columns init in
perf_hpp__init") moves initialization of common overhead column to
perf_hpp__init() but forgot about the gtk code.
So the gtk code added the same column to the list twice causing infinite
loop when iterating it by perf_hpp__for_each_format loop. When I run
perf report --gtk, I can see following messages indefinitely.
(perf:11687): Gtk-CRITICAL **: IA__gtk_main_quit: assertion 'main_loops !=
NULL' failed
perf: Segmentation fault
