I don't know, there are numerous optimizations which can result in totally throwing away the original source. Of course, this would also have the effect of optimizing the source, wouldn't it? But it would probably be much harder to read, and you wouldn't have comments anyway.

The problem is that converting back to C++ code doesn't really help you all that much, because you won't have comments, and you won't have variable names which make sense.

You will have constructs, and code flow.

But those you can still get from ASM disassemblers anyway (like IDA). Knowing the original high-level intent of the programmer (why something was done certain way, variable names, how variables connect to each other) in enough of a way to reconstruct a source is pretty much impossible. C++ really isn't a round trip language ( unlike .NET languages).
