Chris, If I were naughty, I would reply that the MER precisely had memory management problems...


But I rather prefer to thing that the C was bettered, not the language syntax itself, but the compiler which is responsible of writing a correct memory management. Back to ten years ago, when I was working in the domain, there was a suspicion against the C. But if the MER design team estimated that they could do with C, it is that they were confident enough (at least they have more experience than me) that the compilers and OS they used were good enough and would not do some bad trick. So it is a good new after all. Just wanted to know what compiler they used, certainly not the standard compilers used on PCs, but a specific one for VxWorks, which enjoyed a special care for reliability, fitting the reliability level of VxWorks.

I was often angry, writting in various languages of using many softwares, to alway find many bugs and everybody seems to look at such a situation as a normal state of things, lefting software users and programmer spending hours and days to try to guess what is the correct spelling of a command. Of course nobody can pretend to do zero-bug, but the least and first thing to do is, when a bug is found, to recognize it as a bug and try to find a fix without further charge, in place of starting a psychoanalysis of the user.
