Reduced code (two files):

----
module a;
import b;

class LibasyncEventLoop : EventLoop {}


module b;
import a;

struct Appender() { int[] arr; }
struct Tuple() { alias A = Appender!(); }

class EventLoop
{
    auto f() { auto x = [Tuple!().init]; }
}
----

`dmd -c a.d` fails with:

----
dmd: glue.c:809: void FuncDeclaration_toObjFile(FuncDeclaration*, bool):
Assertion `fd->semanticRun == PASSsemantic3done' failed.
Aborted (core dumped)
----

Compiles with 2.068. ICE occurs since 2.069.
