There has been several references that SpaceX "fly" their Falcon 9 computer systems to test for bugs like this. The idea being that as far as the computer is concerned, it is a real flight and should act accordingly. Most of the problems to date, have been related to a mechanical problem. During the first docking, there was a minor issue with the sensor "field of vision" but this was fixed.

The point is that SpaceX procedures seem to be able to prevent similar software bugs in the Ariane 5 from causing a catastrophic abort or failure.
