IIUC in Windows, when the program is stopped, all it's memory is freed, even if the program leaked memory. I don't know about Linux, but I'd be surprised if it weren't the same. This does not mean the OS will not be almost as bad as crashed: if your program leaks too much, you may trigger so much thrashing that your system will become unusable. This did happen quite frequently to me with Windows XP 32 bits. I now use Windows 7 64 bits, and it hasn't happened to me since, but I guess that's only because I haven't tried hard enough :-) -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org
