--- 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?
