Thanks for explanation. I have one question regarding to this topic.
When I use addr2line I get this output:
/home/radarek/work/project/ruby-benchmarks/ruby1.9/vm_dump.c:590
/home/radarek/work/project/ruby-benchmarks/ruby1.9/error.c:213
/home/radarek/work/project/ruby-benchmarks/ruby1.9/error.c:226
/home/radarek/work/project/ruby-benchmarks/ruby1.9/signal.c:540
??:0
??:0

As you see the last two lines don't have meaningful information as
rest lines. Is it ok, or I'm doing something wrong?
