Ben Lancaster · Answer

I figured out what was wrong we had the following `expect` class ```public expect class WeakReference lt T Any gt referred T public fun get T ``` With `actual` implementations that looked like this iOS ```import kotlin native ref WeakReference public actual typealias WeakReference lt T gt = WeakReference lt T gt ``` Android ```import java lang ref WeakReference public actual typealias WeakReference lt T gt = WeakReference lt T gt ```

Ben Lancaster · Answer

The solution was to use an import alias like so ``` android import java lang ref WeakReference as JvmWeakReference public actual typealias WeakReference lt T gt = JvmWeakReference lt T gt ios import kotlin native ref WeakReference as NativeWeakReference public actual typealias WeakReference lt T gt = NativeWeakReference lt T gt ```

Did this only make Dokka fail Or did the compiler fail before that I m surprised it even compiled

Vadim Mishenev · Answer

This is I suppose you did not configure your project correctly You can take a look at my with `typealias WeakReference`

I am actually the author of the Github issue This only happens in Dokka and compiles fine when Dokka is disabled

I agree it s not the best code but it would be great if Dokka didn t crash with a hard to find stackoverflow error Still need to provide a reproducer for the issue as it doesn t seem to be happening in isolation
