I don't think we generate symbols for dynamic data at the moment. There may be uses in the future. I don't know about other JIT programs. If we can include this behaviour it would be great, but I don't have a way to test it. I'd guess if somebody had a valid use case, they would report the issue. Otherwise, the patch as you've written it works great for me.
