------- Comment #3 from mueller at gcc dot gnu dot org 2007-03-21 09:05 -------
both are caused by our well known offender -fivopts.
the problem why the existing workarounds don't work is because the adress is
first converted to unsigned int before +/- modification is done. the traversal
stops at the type conversion. I'm currently working on fixing that.
