Problem is that no RTL is set for the incoming parms in the instantiation of the expansion. It ICEs in gimple_expand_cfg because 'DECL_RTL_IF_SET (var)' returns nullptr for the incoming parms resulting in a failed assertion that SA.partition_to_pseudo[i] is non-null.
Sounds like a problem with how _FUN's parameters are instantiated. I'm not sure why it would be special.
Does using a function parameter pack in the lambda body work currently? If so, how are the expanded parameters different?
