From cc841580aa58ad7498b23e282859d07f8b721e24 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 11 Jan 2011 15:16:52 -0200 Subject: perf top: Fix annotate segv Before we had sym_counter, it was initialized to zero and we used that as an index in the global attrs variable, now we have a list of evsel entries, and sym_counter became sym_evsel, that remained initialized to zero (NULL): b00m. Fix it by initializing it to the first entry in the evsel list.
