`TempPtr` is not necessarily the Temp.data location, it looks like it is modified a h andful of times on line 59 and 65.  

So this is meant to be a 'rest' kinda thing, but the code you changed it to is using the whole 'size'.  I think you need to make `Temp.size()` be `Temp.size() - std::distance(Temp.data(), TempPtr);` (check for off-by-1 please :D).
