Comment (by nomeata):

 I could make it trigger a `T12368: Oops!  Entered absent arg w Stream`;
 test case as `T12368`.

 I think the fix is, if the number of iterations exceeds the limit, to do a
 final run with most pessimistic assumptions about the strictness
 signatures of the things in the recursive group.
