--- Comment #1 from Andreas Krebbel <krebbel at gcc dot gnu.org> --- The problem arises from dr_analyze_innermost not being able to analyze the bitfield access. However, the returned error is ignored in find_data_references_in_stmt and execution continues with bogus values in the data reference object.
