Line number in Google Perftools CPU profiler on MacOSX

Question

I am trying to profile some C++ programs on MacOSX. So I built google-perftools, wrote a program, compiled using MacPorts g++ 4.7, with -g compiler fla

Answer 1

This seems to be related to the address space layout randomization (ASLR) introduced in OS X 10.5

I've filed issue #562 on the gperftools issue tracker. You can disable ASLR by passing -Wl,-no_pie.

Also, if you're not bound to use gperftools, Instruments (comes with Xcode) is worth a try.
