MonoTouch SIGABRT "Ran out of trampolines of type 2" error

Question

I get a SIGABRT / ran out of trampolines error when running my MonoTouch app on a native device (iPad).

This happens pretty early in my app - I'm constructing a section using MonoTouch.Dialog.

        ItemTypeRadio = new RootElement ("Type", new RadioGroup (0))
        {
            new Section ()
            {
                from it in App.ViewModel.ItemTypes
                    select (Element) new RadioElement (it.Name)
            }
        };

Is there a compiler setting for increasing the number of trampolines?

How do I profile this and find out why my app is running out?

Ran out of trampolines of type 2 in '/private/var/mobile/Applications/9A5EE6EB-CAB8-404E-AF2F-E6571C1AC164/iphone.app/mscorlib.dll' (128)

I ended up resolving this by going to the project options :: Build :: iPhone Build :: (config debug / platform iPhone) :: Additional mtouch arguments and adding the following option: -aot "nimt-trampolines=512" — Omri Gazitt
