Comment (by simonmar):

 I think the problem here is that you're trying to use `-O` in conjunction
 with the interpreter, which we normally don't do because optimisation can
 introduce unboxed tuples, which the interpreter can't handle.  I suspect
 that you've uncovered another case that isn't handled when we try to use
 -O with the interpreter, but since we don't have any plans to handle that
 combination I'm not inclined to try to fix this particular problem.

 We will look into why we aren't catching the -O/interpreter combination
 and make it fail in a civilized way.
