--- Comment #1 from Gregory Dushkin <yagreg7 at gmail dot com> ---
The issue is still present in GCC 13.2.1 and appears to only affect the act=
ual
variables but not references to them.
E.g. the code:
```
// test.cc
export module test;
export constexpr int a =3D 42;
// main.cc
import test;
int main() { return a; }
```
would give:
```
$ g++ test.cc -std=3Dc++20 -fmodules-ts -c
$ g++ main.cc -std=3Dc++20 -fmodules-ts -c
main.cc: In function =E2=80=98int main()=E2=80=99:
main.cc:4:12: error: =E2=80=98a=E2=80=99 was not declared in this scope
    4 |     return a;
      |
```

but

```
// test.cc
export module test;
export constexpr int a_ =3D 42;
export constexpr const int& a =3D a_;
// main.cc
import test;
int main() { return a; }
```
compiles successfully using the same commands.=
