how does mainline handle this?  I know it used to get it
wrong (the testcase I sent was filched from gcc bugzilla),
but the bug was marked as resolved, without a link to
the resolving changeset.  Maybe they only solved the
memcpy from a location to itself problem, and not the
overlapping case?

Ciao,
