Subject: a question about debugging chess programs

Is there a fast way to find what is the first step that 2 similiar programs with
source code go different when you ignore specific part.

I have 2 programs that are supposed to be the same except the fact that one save
time in order of moves.

They are not the same.

What I need is a third program that run the first 2 programs in the same time
and tell me the first step that they are different(difference in the procedure
that calculates order of moves does not count).

I do not like to spend hours on trying to figure out the exact place that they
are different when after finding a place that they are different(can happen
after millions of nodes) I find again that they are different for different
unknown reason.

This is exactly what happened to me now.
