------- Comment #2 from rguenth at gcc dot gnu dot org 2009-01-07 12:14 ------- We insist on finding an overlapping SFT even though it might possibly not exist (as in this case where we do an access clearly outside of the object boundary). The fix is to just ignore that and let the operand machinery add whatever memory tag it likes.
