I've also experienced these. The most common cause seems to be a constant which is not "sampled". I don't have a good rule, but sometimes when I start removing components on my design, it starts working, which shows me the element at fault. In general, placing a component which is known to work on its own into a larger system does not cause problems.
Then there's also the times where I reduce the entire system to something trivial like a counter and it still happens. In that case I save copies of everything and reboot. Followed by anger management.
