When we do

    sh_var = bind_variable (varname, value, 0);
    VSETATTR(sh_var, att_nameref);

on a global scope, the variable is not recognized as nameref variable.

As a workaround we can use

    void var_convert_nameref(const SHELL_VAR *sh_var) {
      if (sh_var) {
        char *command = (char*)smalloc(PATH_MAX+1);
        snprintf(command, PATH_MAX, "declare -n %s", sh_var->name);
        evalstring(command, (char *)NULL, SEVAL_NOHIST);
      }
    }
