This reminds me of a bug I had back in ‘98 or so. I was using a Parallax BASIC stamp and could not understand why when I put it to sleep it would sometimes using only 30 uA, and other times 300uA. I kept narrowing down my code until it was utter nonsense, and finally I made it to where if I removed or added a byte of code it would toggle between the two.
I got on the phone with the engineer responsible for the firmware and sent him my code, but I never did find out what the problem was (sorry for the letdown, maybe someone at Parallax remembers and reads Hacker News?). They acknowledged it as a bug, and made a fix. Unfortunately the fix made was to always draw 300uA at sleep!
Fast forward 18 years (!) and from their website it looks like their latest modal draws 50uA, so it was a happy ending after all. The end.
