--- Comment #2 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-05-12 09:11:45 UTC --- Well, XXXevent is scalarized by SRA (-fno-tree-sra gets rid of the error) and I suppose nothing prevents that register to be propagated to other indirect uses. So it might be indeed live over the setjmp call.
