"Notified today that my insulin pump controller has a bug where the leading decimal point will be dropped, ie: changing a dose of .21 units to 21 units. I can reproduce randomly ~1 in 5 times so probably a race condition. Easily one of the worst software bugs I have ever heard of."

#3Wow, that seems extremely serious. In any reql engineering field, this kind of thing would have serious repercussions for the engineer, and not merely the poor consumer.

Let's hope the notified body will stomp on them hard

#5I know the department of defense used to use Ada because it was a “safety critical” language. I feel like when it comes to this devices there should be more stringent guidelines around coding practices. Is that not the case?

However, the document states that "there is no defect identified in relation to the use of this product", which would contradict the Twitter post, so maybe it's a different product or either the poster or the document is wrong.

What brand/model?

#8I can't comprehend how that kind of bug even happens. Not that insulin pumps should have any bugs, but it doesn't even sound like an integer overflow or use after free which is "understandable". Are they doing some kind of scuffed string parsing?

It does not contradict the Twitter post.
They're saying that since there is a confirmation screen, it's the user's responsibility to catch the bug.

The MAUDE database tracks this for FDA. The average consumer can sign up for alerts based on make and model:
