--- Comment #7 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- (In reply to Richard Biener from comment #6) > Agreed. Did anybody bisect what caused this? It only came to light when we added a check in the backend. So I'm not sure a bisect will be that helpful, except if you try with that patch applied to every revision under bisect. Even that might not help as this is likely a long-standing issue.
