That is pretty clever. In a particularly C++ heavy program I was able to find decent splits by starting around where the vtables were stored and searching from there, which was helpful since they also often pointed into the relevant part of the .text section. The repeating floats thing definitely seems to ring true though. For old MSVC it seems like it will emit floats even if they aren't directly referenced, if they happen to be referenced by inline functions that are not used. That adds another challenge if you want to get really close to the actual original source: figuring out what those inline functions actually are instead of just dropping a dummy that references them and is never used :) But I'd say that's extra credit, if you ever got to the point where that was the only remaining debt...
