ABSTRACT:
A method of dynamic memory reclamation for reclaiming memory leaks is disclosed, in which inaccessible heap segments are reclaimed without recompilation or relinkage of an application. The method comprises intercepting a call from an application to allocate or deallocate a heap segment, forwarding the call to the memory manager, passing the memory allocation and deallocation information from the memory manager to a file, performing a conservative garbage collection process using the memory allocation and deallocation information in the file to detect inaccessible heap segments, and calling to the memory manager from the file to deallocate the inaccessible heap segments. These steps are repeated periodically.
