Compilation Error - Invalid_argument("index out of bounds") | DCE full only

When I compile my project it runs through most of it and then outputs this:

Invalid_argument("index out of bounds")

UPDATE: I believe it's something due to dead code elimination. I believe the DCE is eliminating the type somehow and then the macro is bringing it back in. On DCE std or off it runs fine.

I get this when I am targeting HL/C. When I target hashlink, I don't get a compile error, but I get a JIT error where it can't find a function.

After cutting out portions of the project I can get the error to appear/re-appear with the addition and removal of a single function with no body. I have no idea why its happening.

I'm guessing that something is stopping the compiler from emitting the correct number of functions in some way but I don't know how the compiler works internally.

Some more error information would be helpful.

Below is the macro output that when generated makes the error code appear:

```
if (!activated) {
activated = true;
__clientAdd_listener__ = function(__entity__:hcqe.Entity, a:heaps.yojimbo.RemoteClient):Void clientAdd(a);
viewof_ffffffff_heapsyojimboremoteclient.activate();
viewof_ffffffff_heapsyojimboremoteclient.onAdded.add(__clientAdd_listener__);
viewof_ffffffff_heapsyojimboremoteclient.iter(__clientAdd_listener__);
onactivate();
}
```

Below is the same output with the function generation disabled. The error code no longer appears.

```
if (!activated) {
activated = true;
viewof_ffffffff_heapsyojimboremoteclient.activate();
viewof_ffffffff_heapsyojimboremoteclient.onAdded.add(__clientAdd_listener__);
viewof_ffffffff_heapsyojimboremoteclient.iter(__clientAdd_listener__);
onactivate();
}
```

The above was printed with the Haxe macro printer.

Simply assigning the anonymous function in the macro makes the error code appear.
__clientAdd_listener__ = function(__entity__:hcqe.Entity, a:heaps.yojimbo.RemoteClient):Void clientAdd(a);

If I change the type the error code also goes away.

Here is the Haxe -v output tail:
```
