This is sad. A comment was added, by me, that doesn't seem correct since we allocate a large array that can cause a GC and collect one of the objects we are using.

runtime/src/coreclr/vm/interoplibinterface_comwrappers.cpp

Lines 347 to 359 in e9869c3

	// Allocate enumerable type to return.
	gc.arrRef = (PTRARRAYREF)AllocateObjectArray((DWORD)localList.Size(), g_pObjectClass);
	// Insert objects into enumerable.
	// The ExternalObjectContexts in the hashmap are only
	// removed and associated objects collected during a GC. Since
	// this code is running in Cooperative mode they will never
	// be null.
	for (SIZE_T i = 0; i < localList.Size(); i++)
	{
	ExternalObjectContext* inst = localList[i];
	gc.arrRef->SetAt(i, inst->GetObjectRef());
	}
