Does anyone know of a tool that allows two copies of a binary to be run at the same time (in lockstep, instruction by instruction) and monitors the memory image of the binaries for discrepancies, or divergences in control flow?
Yet again, I'm in the situation where code is producing subtly difference science results with different optimisation settings and I need to track down where it starts. Valgrind contains most of the raw capabilities to implement this (I think), but it's way beyond my hacking capabilities. Any thoughts, comments or tool suggestions gladly received.
