Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at redhat dot com, | |rguenth at gcc dot gnu.org --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- It looks like the C++ frontend builds COMPONENT_REF with IDENTIFIER_NODE operand one and the middle-end is not expecting this. Maybe we call operand_equal_p before layout is complete? I suppose we could guard operand_equal_p for this case but then handing invalid GENERIC to the middle-end is suspicious. Jason?
