Fixing Memory Leaks

Once you have obtained a memory leak report, there are some general guidelines for fixing the memory leaks. The most important thing is to determine where the leak is. The leak report tells you the allocation trace of the leaked block, the place where the leaked block was allocated. You can then look at the execution flow of your program and see how the block was used. If it is obvious where the pointer was lost, the job is easy; otherwise you can use showleaks to narrow your leak window. showleaks by default gives you only the new leaks created since the last showleaks command. You can run showleaks repeatedly to narrow the window where the block was leaked.
