I am encountering some issues with using Valgrind 3.6.1 Callgrind on
Centos Linux 5.5. I am using a simple test program using the Fibonnacci
function(shown below). However, when I run:
/home/frankc/DQTTest/valgrind-3.6.1/coregrind/valgrind --tool=callgrind
--dump-instr=yes --simulate-cache=yes --collect-jumps=yes
callgrind complains about std::ios_base::Init::Init() (in
/usr/lib/libstdc++.so.6.0.8) and we obtain no profiling output. Is this
issue specific to Centos Linux 5.5 or am I doing some wrong? I can send you
my makefile if you wish. Is there a workaround to this problem? The
Valgrind/Callgrind error messages are shown below. Thank you.
