MonoTouch SIGABRT “Ran out of trampolines of type 2” error

问题

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)

回答1:

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"

You should copy-paste your comment into an answer and mark this question as answered (it's ok to answer our own question on stackoverflow) as it will help other people looking for the same issue.

You likely find out about this page while looking for this: http://docs.xamarin.com/ios/troubleshooting#Ran_out_of_trampolines_of_type_2

I modified Mono's runtime (used in MonoTouch) to print this URL when hitting this condition (type 0, 1 or 2). Hopefully this will make it a bit faster to solve this for other people.
