So it is your claim that a piece of software which passes the certification procedure and the conformity tests is a correct Ada compiler? Suppose I coded an Ada compiler which, each time it compiled a program, picked an arbitrary even number, and if it determined that the number was not the sum of two primes then deliberately translated that program incorrectly. Is that a correct Ada compiler? >> I submit that >> specifying the requirements of a program is identical to >> writing that program, > > It is not.

And so is having software that is built in ad hoc ways and written in C++ instead of Ada. > No need for that, they must be liable for damages of certain extent. But they already are.
