[Issue 12269] Unittest within template struct scope is not executed

After some more testing I have some more information which may help.

Firstly, the problem is also present in DMD 2.064.
(I have no DMD older than this)

Secondly, I found that the unittest within struct scope is run only if S is
instantiated in a module scope unit test.

For example the following incorrectly compiles and executes without an error:

$ rdmd --main -unittest -debug utbug.d
---
// utbug.d
struct S(T) {
    unittest {
        BUGME("should not compile"); // <<-- should break the build
    }
}

unittest {
}
----

But instantiating S!int() in the module scope unit test works as expected:


$ rdmd --main -unittest -debug utbug.d
utbug.d(5): Error: undefined identifier BUGME
utbug.d(9): Error: template instance utbug.S!int error instantiating

---
// utbug.d
struct S(T) {
    unittest {
        BUGME("should not compile"); // <<-- Should break the build
    }
}

unittest {
    auto s = S!int();
}
----

Thanks,
ed
