 		 #177780 - If a new version does not work find out why
Responding to: ???'s previous message
Erik Malund said:
If a new version does not work find out why do not just go a revison back.

But one of the most powerful tools to find out why is to do a comparison against the "last known working" version!

If something was working, you changed it, and now it doesn't work - it is a fair assumption to start with that the problem is in your changes!


I have seen people spending an inordinate time analyzing what was changed, which will not tell you what is wrong

Very often, it will, at the very least, give you a very good idea of where to look for what's wrong!

Even when it isn't the "new" code itself that's wrong - just its effect on (buggy) "old" code - knowing where the changes are is still useful in focussing the debug attention.
