In the 32 years or so I've been programming, I think I've encountered
problems in programs that really weren't >>my<< fault (as opposed to
bugs in a compiler or even a mature library) fewer than a dozen times.
So the odds were pretty good. Especially for something like gcc+PVM,
which is a combination widely enough used and old enough that finding a
new, unfixed, egregious bug is really really unlikely.
It always helps to get another pair of eyes on buggy code though, and
the list contains a lot of pairs...;-)
