The exception trace (produced with polyml-5.3.0) points to 
src/HOL/Tools/Quickcheck/random_generators.ML: compile_generator_expr_raw 
/ iterate_and_collect. It think it is coming from "compile" defined as 
Code_Runtime.dynamic_value_strict.

It is very difficult to figure out where it really happens, due to all 
these indirections of Random_Engine.run etc.
