--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think the problem is that build_va_arg forces ADDR_EXPR with a slightly
different type than building ADDR_EXPR of expr would normally use, and due to
the C++14 extra paren reference we have ADDR_EXPR with the type we want of
INDIRECT_REF of NOP_EXPR (reference) of ADDR_EXPR, and the ADDR_EXPR of
INDIRECT_REF is cancelled early and we get the reference to array type we
really aren't prepared to handle.
