Native/managed repro projects and crash output
I'm attaching a full repro and crash output. It contains a native dylib which invokes the managed protocol implementation.
Apologies on the long delay in response to this bug. It was misfiled and thus overlooked. I've taken a look, and at first glance it appears to be a problem still.
Rolf - I think this is a runtime issue? Do you think this is something that is your area? Else, bounce back.
This works fine with maccore/master, so it looks like we've fixed it quite recently (126.96.36.199 still crashes).
We are trying to verify this issue, but we are not sure about the steps to check or verify this issue.
I checked this issue with the attached sample, after migrating it in to Unified API getting build error. Here is the screencast for the same: http://www.screencast.com/t/Wn23LAhGHZQu
Could you please share steps check this issue? So that we can verify it efficiently.

* Download the attachment from comment #2
* Open TestParameters.sln from inside the zip
* Chose "Migrate to Xamarin.Mac" when Xamarin Studio asks for it
* Clean & rebuild & run the project.
* It should not crash at startup.
There is no need to convert the app to Unified to verify this bug.
