From 91557e847dbc715acf2d847a1ffec63f71b00b65 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 30 May 2012 12:25:52 -0300 Subject: perf report: Use the right symbol for annotation In non symbolic views, i.e. --sort without "symbol", as in: perf report --sort comm We're segfaulting in the --tui because we're testing the symbol resolved and then trying to use the symbol on the histogram entry where we're coalescing all hits for a COMM, and the first hist_entry for a comm may have a NULL symbol, i.e. the RIP didn't resolve to any symbol. In this case we're segfaulting, fix it by testing against the symbol in the histogram entry.
