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);
}
}
