If you aren't deliberately trying to miss the point, TFA claimed "only idiots make buffer overflow error" and the OP is implying it's not just the idiots, but very smart people(look up the names) who make buffer overflow errors as well.

It's a simple rule. Don't write buggy code. The issue has been known for decades and everybody should be aware of it by now.

I am trying to find the buffer overflow in DJB's code. I am more interested in the fact if it was a simple error(give too long an input and it goes kaboom), or a complicated one. My intuition is it is the complicated kind. DJB is known to actively use his own implementation of stdlib and strings which are coded from scratch to be secure than the standard counterparts.
