according to the official report, Ariane 5 bug was an overflow during a conversion caused by a too large lateral speed in ariane 5 cinematics. Ultimatly, this bug was due to the lack of 'requirement tracability' between ariane 5 and ariane 4. Another ultimate cause was the missing of proper testing simulation software.
