Answer 1

The height mapping node certainly isn't supposed to crash, but it is meant for a specialized application and you probably shouldn't be using it :) In any case, a backtrace would be required to get a better idea of what is going on.

What you really want is probably starting a standard mapping setup however, which should not crash in the first place.
