That's wrong, KVO doesn't make a strong reference, as you can tell from the 'freed when KVO was still attached to it' message, however it trips up Leaks. My handwaving belief is that KVO information is kept in a separate table somewhere and the Leaks process sees the A or B pointer in that memory and conservatively assumes the objects are referenced. I should probably file a but one day.
Please file a bug report. Disguising pointers in side tables so leaks doesn't see them is routine.
