Comment(by bgamari):

 Oh dear. I do know that unfortunately the program is sensitive to the
 number of replications passed to replicate. With 30 iterations, the
 program crashes for me roughly half the time. With 28 it practically never
 crashes. Perhaps try raising this number?

 Moreover, the case Test2.hs that I'm about to attach is slightly more
 minimal and also crashes. This demonstrates that, as expected, the
 newtypes don't contribute to the crash, nor does the (>>=); it's strictly
 a matter of how many numbers are generated.
