I guess Cyrille would have told us.

Fun story about the buggy realloc, there should be an issue of that kind in YAFFS or in the OS, but probably related to some of the hardware modifications.

It reminds me another story, I think it’s true (confirmed by Wikipedia): the first flight of the rocket Ariane V, which was strongly mediatized, was a fail and ended by the destruction of the rocket.
After a complete analysis, they found that the reason of the fail was an integer overflow in the inertial unit software. They did not expect any bug in this part of the software because it was an old piece of code used without any failure with Ariane IV. For Ariane IV, the inertial unit of the concerned stage was used a certain amount of seconds. But Ariane V being much more powerful they planned to use the same stage during a much longer time. The program was late, but being mediatized they did not want to postpone the first launch. The testing strategy was limited to new components and basic tests, and everybody trusted the code of the old inertial unit. Being used longer than in the previous configuration, the overflow appeared, and was not well interpreted by the central unit, leading to confusion of the orientation of the rocket and, finally, disintegration.
The flight was not carrying humans, and nobody was injured, excepted the pride of the engineers.
I was young at the time and did not work for the Arianespace company, but since this day I don’t accept any software to be committed to production without a 99,9% testings cover. Thanks to TDD this is now highly facilitated.
