"Finding" them is a warning signal of a poor programmer if and only if the scare quotes mean that they have not actually researched the problem sufficiently to prove that the problem is in one of those areas.
These legitimate bugs do exist, and some of us have a talent for finding them with annoying frequency.
Less experienced programmers often "want" to find bugs in the compiler/OS/whatever because that way it's not their fault, and they lack the skill to track down difficult problems in their own code. More experienced programmers realize that finding bugs outside of your own code is often a disaster because frequently there's nothing you can do to fix it.
