This might be only a question of definition, but maybe there's a consensus?Given the situation, software Foobar Plus is under construction, we're not working on an update, but on the first release of it.Now, a specific feature(A) was implemented;Feature(A) caused a unwanted behavior in feature(B). It has no influence on feature(A), but is caused by it.Feature(B) isn't implemented yet, the behavior got noticed due interpreting debug logs.The question now is; is this unexpected behavior called a bug, or just a change in feature(B)'s environment?Edit:This question isn't about blaming anyone but about finding the proper definition for this case.
Is unwanted behavior, while work is in progress, declarable as a bug?
