(But they should have fixed the above method just recently.) git clone https://github.com/LouisBrunner/valgrind-macos.git cd valgrind-macos ./autogen.sh ./configure –prefix=/where/you/want/it/installed –enable-only64bit make sudo make install Enjoy!
As suggested, there already exist excellent tools like Valgrind to do this. Further: I would like to do this without any external utilities for practice This is interesting and I am sure would be fulfilling, You can use macro trick to detect such memory usage and leak errors, in fact write your own neat leak … Read more

In Xcode 4 select Product/Edit Scheme from the top menu then click on the “profile” button on the left. On the “info” pane you will see a setting for Build Configuration- set that to … Read more
