Ada or not, Nope - a while back we did a comparison using a rather well known study into the root causes of programming errors in 'C' (I'll reply with the exact reference when I get to work on Monday, if you want) Roughly 50% of the errors either could not occur in Ada or would be caught by the compiler. C++ also (almost by definition) contains the same root causes as 'C'.
