19.1 Memory Tools
Use the following memory debugging tools
The "MPatrol" is a very powerful memory debugging tool. It is at http://www.cbmamiga.demon.co.uk/mpatrol and at http://www.rpmfind.net go here and search mpatrol. If you are using Linux then you must download the mpatrol*.src.rpm file from the rpmfind.net. To update the mpatrol*.src.rpm to latest version, you can use the old mpatrol.spec file and latest mpatrol*.tar.gz file to rebuild new *.src.rpm.
On Linux contrib cdrom see mem_test*.rpm package and at http://www.rpmfind.net go here and search mem_test.
On Linux cdrom see ElectricFence*.rpm package and at http://www.rpmfind.net go here and search electricfence.

RE: Fuel leaks :)

Если прожект на C/C++, то можно использовать библиотеку libgc из пакета boehm-gc ( Garbage collection and memory leak detection for C and C++ ). Сам пользуюсь (в FreeBSD есть в портах) и оччень рекоммендую ;) - http://www.hpl.hp.com/personal/Hans_Boehm/gc/
