Abstract
A program control flow trace is obtained from a processor trace module, which may be hardware based, and is used, in combination with debug information and information from dissassembly of basic blocks, to identify candidate store instruction(s) which produced a memory corruption. The candidate store instruction(s) and links to a software program may be used to further debug the memory corruption and/or to instrument the software program to identify basic block(s) which produced the memory corruption in future executions of the compiled software program and/or to track debugging of the software program.
