There was a member (Socrates I think?) here many many years ago who had that happen in a car he bought - either cross threaded\damaged the threads and the bolt wouldn't come out. It was a saga and a half that he detailed how to get it out and plenty of folks chimed in about how they'd never seen it happen before. I do not know if he had to have the crank fixed or not.
So to answer your question, I am sure it is possible but is extremely unlikely per the many experienced folks around here (and my personal experience too).
