[PATCH] D45382: [CodeGen] Avoid destructing a struct type that has already been destructed by a delegated constructor

[John McCall via Phabricator via cfe-commits]

If that's the problem, then I think the right design is for CallArg to include an optional cleanup reference for a cleanup that can be deactivated at the instant of the call (we should assert that this exists for parameters that are destroyed in the callee), and then for forwarding it's just a matter of getting that cleanup from parameter emission to forwarding-argument emission.
