<pre>Another reachability bug. See <a href="https://godbolt.org/z/33KxaYj8h">https://godbolt.org/z/33KxaYj8h</a>, which GCC
accepts: <a href="https://godbolt.org/z/do9Yz3sds">https://godbolt.org/z/do9Yz3sds</a>.
mod.cpp:
```C++
export module mod;
export template <class> inline constexpr bool b{false};
template <> inline constexpr bool b<int>{true};
```
test.cpp:
```C++
import mod;
static_assert(b<int>);
int main() { }
```
Output:
```
test.cpp:2:15: error: explicit specialization of 'b<int>' must be imported from
module 'mod' before it is required
static_assert(b<int>);
^
mod.cpp:3:35: note: explicit specialization declared here is not reachable
template <> inline constexpr bool b<int>{true};
^
1 error generated.
