`import * from as` pattern in section not working

[huangqinjin]

a.hexpat

import std.io;

char a @ 0;
std::print("a in module [{}]", a);

testing code

import std.mem;
import std.io;
import * from a as A;

auto data = std::mem::create_section("data");
std::mem::copy_value_to_section("AB", data, 0);

char c @ 0;
A a @ 0 in data;

std::print("c [{}], a [{}]", c, a);

a in module got wrong value, and on UI there is runtime error.
