A leak is always a bug in the application. More specifically, a leak is a block of memory that was allocated, but will never be freed. If all pointers to that block have gone out of scope or were assigned to point elsewhere, the application will never be able to free that piece of memory. A small leak may be acceptable in a desktop application that will exit at some point, since an exiting process returns all memory to the operating system. But in a long running embedded system, it is often necessary to guarantee that absolutely no leaks exist-a non-trivial challenge. In this paper, I am going to discuss puddle hunting and leak location.
