From e345fa185ad805cbd3be3397b3cba32bc42ef571 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 13 Oct 2011 09:06:54 -0300 Subject: perf top: Remove entries from entries_collapsed on decay We were removing only when using a --sort order that needs collapsing, while we also use it in the threaded case, causing memory corruption because we were scribbling freed hist entries, oops.
