--- Comment #4 from Tom O'Connor <toconnor at forcepoint dot com> --- Bitfields seemed to work fine in all GCC prior to 6, FWIW. The same attached source code when built with other GCCs prior to 6 generates DW_AT_data_member_location = 0 for all the fields as expected. Only 6 gets some of the fields "wrong".
