--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to vries from comment #2) > I think the test-case is reading an undefined value from n->next, but that's > easy enough to fix with an intializer for node. Since node is a global variable, it is zero initialized so there is no reading from an uninitialized area.
