Test case

Repro:
* Run the attached test project on device (in 32-bit mode).

Result:
> Attempting to JIT compile method '(wrapper delegate-invoke) <Module>:invoke_bound_CGSize_intptr&_intptr_intptr_intptr (intptr,intptr,intptr)' while running with --aot-only. See http://docs.xamarin.com/ios/about/limitations for more information.
 (System.ExecutionEngineException)

If SizeWithAttributesDelegate is modified to return void, this exception does not occur (but obviously the test project crashes just after, since the arguments end up all wrong).

@Zoltan, can you have a look?
Comment 2 Zoltan Varga 2015-05-14 12:38:33 UTC
Fixed in mono master e9931382272870b086401d726147f59ea72a696e.
Comment 4 v7d 2015-05-26 15:46:51 UTC
What is the expected release for this fix?
Comment 7 Shruti 2015-05-27 09:16:52 UTC
Before verify, I need to reproduce this issue so I have deployed attached Test case sample project on 4S 32 bit device. It is deploying successfully on device and displaying text 'here is a test'. 

I have tried it with X.iOS 8.10.0.256, 8.10.0.258, 8.10.0.303

Can you please let me know how I can able to reproduce this issue.

@Shruti, can you try this project instead?
Comment 9 Shruti 2015-05-27 10:58:03 UTC
I have tried again with project given in comment(8), unfortunately still not able to reproduce it. I used X.iOS  8.10.0.258, 8.10.0.303 to reproduce this issue.
Comment 10 Rolf Bjarne Kvinge [MSFT] 2015-05-27 11:01:28 UTC
@Shruti, That's very strange, I have 8.10.0.267 and the app crashes on startup on my iPad Air (Debug configuration). Can you make sure you clean the solution between each XI re-install?
Comment 11 Rolf Bjarne Kvinge [MSFT] 2015-05-28 04:55:51 UTC
@Sebastien, can you try the project in comment 8 on device and see if it crashes for you at launch?
Comment 12 Sebastien Pouliot 2015-05-28 09:13:43 UTC
With 8.10.1 (macios-cycle5's head) on an iPod Touch 5th gen (32bits) I get this:

2015-05-28 09:08:20.233 MethodSwizzle[1000:432606] Unhandled managed exception:

which is identical to the first reported exception.
Comment 13 Rolf Bjarne Kvinge [MSFT] 2015-05-28 09:21:45 UTC
@Shruti, can you try removing the app from the device before cleaning the solution and running again?

@Shruti, can you try this test project now?

If it still doesn't fail, please get the output in the Application Output (nothing else is needed).
Comment 15 Shruti 2015-05-29 09:26:36 UTC
First I have reproduced this issue with attached project bug29970-b using X.iOS  8.10.0.256 . Getting exception when application is launched.  Here is the screencast for same : http://www.screencast.com/t/jiWDmffK8

Then I have verified this issue with X.iOS  8.11.0.868. Now it is working fine with this build. I am able to deploy and launch the app successfully.
