If we add more bit-fields, that is now fixed in 4.0.2 and 4.1.0 by:
2005-08-04  Richard Henderson  <rth@redhat.com>

        PR 21529
        * params.def (PARAM_SRA_MAX_STRUCTURE_COUNT): New.
        * params.h (SRA_MAX_STRUCTURE_COUNT): New.
        * tree-sra.c (decide_block_copy): Use it.  Disable element copy
        if we'd have to instantiate too many members.

But the orginal code is not fixed as we don't have too many members.
