--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
The constructor is invalid:

(gdb) p debug_generic_expr (exp)
{.D.2102={.x={.D.2071={.value=1}}, .y={.D.2071={.value=1}}}, .(struct A *) this
+ 8={}}

the element index has to be a FIELD_DECL - 'this + 8' is not allowed here.

C++ frontend issue.
