Clang 20 compiler C++ frontend command failed due to signal

• I cannot decipher what is going wrong here.
• This happened while migrating my project from Clang 19 to Clang 20.

I had the following main.cpp

struct First {
    int value{ 42 };
};

struct Second {
    std::reference_wrapper<const int> ref;
};

auto main() -> int
{
    constexpr int result =
        core::app::Builder{}
            .extend_with<extensions::ResourceManager>()
            .use_resource(First{})
            .inject_resource([](const First& first) -> Second {
                return Second{ .ref = first.value };
            })
            .extend_with<extensions::Runnable>()
            .run([](auto app) {
                return app.resource_manager.template get<Second>().ref.get();
            });

    return result;
}

If I put First and Second in an unnamed namespace, it works.

namespace {

struct First {
    int value{ 42 };
};

struct Second {
    std::reference_wrapper<const int> ref;
};

}   // namespace

Unfortunately, preprocessed source that Clang generated doesn't include core.app and extensions modules. Can you reproduce this using #include directive? You can also try to provide sources of those modules, but frankly, a self-contained reproducer is much easier for us to work with. Assuming that this is not a bug in modules implementation, of course.

Unfortunately, preprocessed source that Clang generated doesn't include core.app and extensions modules. Can you reproduce this using #include directive? You can also try to provide sources of those modules, but frankly, a self-contained reproducer is much easier for us to work with. Assuming that this is not a bug in modules implementation, of course.

This is a bug with modules if I had to guess. I had other problems with them and missing unnamed namespaces. You will find a similar definition of First and Second inside utility.containers.StackedTuple module.
The modules are pretty easy to navigate given this source directory. Module names match the directory structure (and filename).
