--- Comment #3 from Jason Merrill <jason at gcc dot gnu.org> ---
The testcase in comment 1 works on trunk and current 7 branch. The original
testcase looks ill-formed to me; [dcl.constexpr] says that a constexpr function
can't define a variable with static storage duration, and I think the same
applies to statement-expressions, for the same reason: when we optimize to a
constant value, we no longer have the declaration, which leads to link errors
like this.
