I work for the company audited and I'm sure the audit is post-1995 by some margin (when I was no longer working there), and by your own argument, by 1990 the compilers were pretty close to standard C, yet this study still found a 10*defect rate in C than in Ada... and a 100* defect rate compared to SPARK... Yet, this sort of report seems all to common to me. Every language since 'C' has had at least 1 report that shows how brilliant it is at compared to 'C', yet 'C' is still the most widely spread language. Why? I think we perhaps need a psychologists view rather than looking at language differences. Are humans 'hooked' on tracking down /really/ tricky null pointer dereference problems? Is it really just a fight for 'silver back status' coz 'my programs compile to 1 long word less than yours'?... Cheers -- Martin
