That's nonsense as "rss" should be "rse" and "rse" is not available in that
function - just expr2.

I think that problem is closely related to PR 51976: For deferred-length
components, using ts.u.cl->backend_decl directly is not possible; one needs to
have "var->component" and not "component".
Here, the issue is rather similar. I believe that one needs some conversion
function which makes string_length available by walking an expr. (It should
also work for the "length" part of parameterized DT.)
