In case you wondering this is all (including having leafified working)
caused by my little patch to tree-ssa.c:

2004-06-02  Andrew Pinski  <pinskia@physics.uc.edu>

         PR tree-optimization/14042
         PR tree-optimization/14729
         PR tree-optimization/14736
         * tree-ssa.c (tree_ssa_useless_type_conversion_1):
         Check the type which the pointer points to
         instead of the pointer types.


Thanks,
