Based on trexx's posts and Simon's post, I would say that the pinhole issue is the leading suspect currently.
I've shot multiple rolls of B&W and colour in this pinhole camera and have never seen those spots before. I have also re-shot in the same environment where I had this problem and the spots are not present on that roll. I'd say it's a developer problem.
I am familiar with solar flare in pinhole photography when shooting into the light. It looks a bit like lens flare but that's not what is happening on the roll of film in question.
