From 0849327d13a0bd7f6512b7c21f4b3e79efb2076d Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 11 Feb 2011 12:09:54 -0200 Subject: [PATCH] perf report: Fix initializion of annotate symbol priv area We only allocate it when in TUI mode. In --stdio mode unconditionally initializing this area leads to memory corruption.
