--- Comment #1 from kinke@gmx.net ---
The `double` field is required to make the Tuple struct template non-zero-initialized, so that the init symbol is actually required. You'd have the same issue with an `int expand = 1` field.

For some reason, the TypeInfo for Tuple is emitted into the `main` module, but the init symbol isn't.

Another question is whether the unittest is actually supposed to be 'instantiated' by the import of the module alone. The PosixEventDriver class template isn't instantiated in the main module, so I'd say it should not.

A slight variation with opEquals and opCmp:

----
struct Tuple()
{
    bool opEquals(const Tuple other) const { assert(false); }
    int opCmp(const Tuple other) const { assert(false); }
}
----

Rest as above.

Output:
