There is a non-sequitur there.
It is true that the best a type system can do is give you fewer (not less)
run-time problems, not none.  Amongst other things, 1/0 is well-typed.

However, it does ***NOT*** follow that a crash is acceptable behaviour.
What's probably occurring is some type of stack overflow.  Other programming
languages manage perfectly well to catch such errors and give you an
intelligible diagnostic.  Just crashing and leaving it to the operating
system to tell you why just isn't good enough.  Clean gets away with it
because it's free.
