------- Comment #5 from ebotcazou at gcc dot gnu dot org  2010-04-16 15:17 -------
Created an attachment (id=20398)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20398&action=view)

        * tree-sra.c (bitfield_overlaps_p): If the length of the element is
        self-referential, try to compute an upper bound.
