Bus Error on Sparc Solaris since r46884
Description
Since r46884, bus error occurred on Sparc64.
PACKED_STRUCT_UNALIGNED generally should always be used, and PACKED_STRUCT generally should never be used unless it is really needed.
I think existence of both PACKED_STRUCT and PACKED_STRUCT_UNALIGNED is confusable and can always be a potential source of bugs.
