This is, in general, an aliasing violation nearly guaranteed to fail. Instead try *return = VCE<In>(fn(mem, VCE<In>(*desired), model)) where VCE<T>(E) is a VIEW_CONVERT_EXPR with TREE_TYPE = T and a first operand expression of E. But in particular, the actual stores and loads happen in the original type. r~
