From d50bf78ff69297d3f60aa778c272acc8e5f59a19 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 6 Aug 2013 14:14:13 +0900 Subject: perf ui/gtk: Fix segmentation fault on perf_hpp__for_each_format loop 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.
