Hi Jack,

"paying attention next time"?  That's not the right answer.

Please make sure that there won't be a next time.

The big evil with LLVMs is not the fact they are making mistakes but the extreme level of confidence at which they are presenting these mistakes - like no human would do.
That's why we tend to fall so easily into taking their trash for granted.
