Comment (by nomeata):

 The difference you marked is a result of
 changeset:c001bde73e38904ed161b0b61b240f99a3b6f48d/ghc. But I believe it
 is not the cause of the problem, as the state hack would, if I understand
 it correctly, assume `State# RealWorld` to be one-shot independent of
 whether that annotation is present in the unfolding or not.
