Abstract
A method using a computer and a system for dynamically detecting leaked memory space in a computer program. The computer program comprises instrumentation routines for communicating runtime memory space conditions to a dynamic debugging system and has a memory space for storing dynamic data values. A dynamic leak search is performed for tracking allocated memory space using reference counting. A static leak sweep is performed for scanning blocks of the memory space to determine whether each such block of the memory space is reachable from another such block of the memory space.
