The alias defined here with the
.set
directive doesn't actually define a symbolic alias that the linker respects in all cases. The resulting standard library dylib does contain a reference to the aliased symbol with the correct value, but the resulting symbol is not actually considered relocatable by the linker. Thus, its value may not always get fixed up properly.Work around this by dropping the alias for now - directly use the type metadata for Swift.__EmptyArrayStorage instead.
