I checked that this cast helps to fix a problem with ptxas with shared/global memory refs. I'm not saying that this is the best solution, but better to have a fix while the final solution is not landed. Plus. maybe, it will fix some other potential issues until the `$ref`s will go away. Maybe need a new attribute to avoid early optimization of the internal vars.
