This depends on your definition of "bug". I think, in the classical sense, a bug is something that you understand both the cause and the resultant undesired behaviour and, as of consequence, you can reproduce the chain of events.

Given that definition, I would be disinclined to agree with calling it a "bug".

However, I would also like to point out that we're getting so nuanced in terms that we're, quite literally, dropping the notion of lauding the attempts of the OP to go down the road of wanting to deduce the problem, themselves.

I disagree. If you have to understand the cause of undersires behaivor before a bug can be said to exist, then debugging is a prerequisite to a bug existing.

If I write a program that computes 2+2 and it tells me the answer is 5, that’s a bug. Why is irrelevant until I want to fix it.
