I think this was introduced by:
2005-06-07  Sebastian Pop  <pop@cri.ensmp.fr>

        PR 18403 and meta PR 21861.
        * Makefile.in (tree-chrec.o): Depend on CFGLOOP_H and TREE_FLOW_H.
        * tree-chrec.c: Include cfgloop.h and tree-flow.h.
        (evolution_function_is_invariant_rec_p,
        evolution_function_is_invariant_p): New.
        (chrec_convert): Use an extra parameter AT_STMT for refining the
        information that is passed down to convert_step.  Integrate the
        code that was in count_ev_in_wider_type.


The reason why I say that is because it worked on 20050603 but failed on 20050610.

I also think this is the cause of PR 22212 too.
