Comment (by dolio):

 Ah, sorry. Data.Array.Vector is from the uvector package, which is
 available on hackage. If that's unacceptable, I can try to construct a new
 test case, or make a dummy module as you said, but my initial attempts
 writing do-nothing loops similar to the one above didn't trigger the bug
 (so obviously results are quite variable).
