Core Analyzer
A power tool to debug core dump, memory corruption, optimized code.
... file or a live process's memory, core analyzer is able to scan the target's heap data for memory corruption, search the whole address space for data object's references, or analyze memory pattern. It is thorough, labor-free, and insightful. I use the tool on daily basis and it is proved to be invaluable to debug many tough issues.
The tool supports x86_64 architecture including Windows/RedHat/SUSE/MacOSX (32-bit and 64-bit).
