Henning Meyer: Investigating C++ Core Dumps in Depth

This time we are having a shared event in cooperation with the Greek C++ Community Group [GRCCP]:

Core Explorer is new a tool for analysing core dumps. Debugging with core dumps comes with several challenges when compared to debugging a live process. Core Explorer offers new methods to find C++ objects in program memory and to reconstruct heap allocations. This can be used to investigate memory corruption and memory leaks in C++ applications, particularly when combined with time-travel debugging.
Outline:

1. Generically traverse any container using debug information and decompilation
2. Reverse engineer heap allocations from memory contents and libc debug information
3. Run a conservative garbage collector in leak detection mode
4. Find the exact instruction causing a memory leak with time travel debugging (WIP)
