If you are using raw_format such errors should be expected,
as no alignment is done. (raw_format is pretty much a
debugging feature and probably should be removed...)

If you're using XDR or GIOP, it is definitly a XTL bug
and thus I'd appreciate a small test case that makes it happen.

I don't think so, unless it stores anyting other than single
byte characters.
