Date: 2010feb7 OS: Windows Language: C/C++ Q. My program has a memory leak but I am deallocating everything I allocate. How can I fix it? A. It could be that your memory is getting fragmented. Use pools / private heaps. For example if your program reads a file, parses it into chunks that are new'ed then delete's all of them. And does this many times. You can put all those new's into a pool and free up the entire pool when done with the file. On Windows use:

HANDLE hHeap; // Make the heap that will be used for one file hHeap = HeapCreate(0, 10 * 1024, 0); // Initially 10K, no upper limit LPVOID pChunk1 = HeapAlloc(hHeap, 0, size_of_first_chunk); LPVOID pChunk2 = HeapAlloc(hHeap, 0, sizof_second_chunk); ... // When done HeapDestroy(hHeap);

There is also Boost.pool On Linux, you can use the Apache Portable Runtime pools: http://apr.apache.org/docs/apr/0.9/group__apr__pools.html
