Also frequently, when the assertion hits, the Visual Studio instance hard-locks and I have to kill it through Task Manager.

4 years ago Out of curiosity: In other projects, I have seen issues being transferred "inline", so it just changed the project it's visible in. This here is a verbatim copy (with changed authorship). Is this due to the issue being moved from one org to another?
whitneyschmidt
commented
4 years ago @Tragetaschen Yep, that's exactly what's happening :)
We'd be able to reassign it without the copy/paste if we were moving to another repo inside of xamarin, but mono/mono is a completely separate repo so we create a new issue and c/p the issue history.
Your issue was transferred because it looks like a mono runtime issue, not an SDK issue with Xamarin.iOS or Xamarin.Mac.

One bit of info that wasn't copied from the original issue filed in x-ios: It looks like this line is getting hit: https://github.com/mono/mono/blob/87ef5557017a8d822ae31587846a54fcd66daf1b/mono/mini/mini-arm64.c#L5439

3 years ago @nor0x Could you upload a small sample solution that reproduces this issue and share where exactly you're setting breakpoints?
It also looks like you're using VSWin + VSMac, could you share the version information for both?
I wasn't able to reproduce this using VSMac + an iOS device.

If you have interest in resolving this, please create a small sample application that reproduces it and attach it here.

If it's possible, could you create a small sample application that reproduces the problem and upload it here? That is the best way for the team to investigate.

3 years ago I tried to create a small sample app. Unfortunately, I was not able to reproduce this issue with it.
I have seen the issue when I set the breakpoint within a constructor of a class which is instantiated via AutoFac within the AppDelegate.FinishedLaunching(UIApplication app, NSDictionary options) method. Breakpoints at other places work correct.

3 years ago @alanspires You are correct, it does fix the issue - but opens another (minor, since it is not a crash): The XAML HotReload in Visual Studio stops working when using Xamarin.iOS. Is there any known workarounds for that?
Deepfreezed
commented
3 years ago Thanks, disabling "Enable the Mono interpreter" worked. Hot reload does not work now, it's at least something.
znelson32
commented
3 years ago This saved me after hours of troubleshooting. Disabling the Mono Interpreter solves the problem, but also removing all breakpoints and then adding a few back works, too. Ultimately there's an issue with Hot Reload as that crashes randomly even with Mono Interpreter enabled.

2 years ago Hi there, we are working on a very complex project and now we are facing the same issue. Disabling the mono interpreter fixed the problem, not a real solution tho.
Microsoft Visual Studio Professional 2019 Version 16.11.2 Xamarin 16.11.000.174 (d16-11@e8f56f1) Xamarin.iOS and Xamarin.Mac SDK 14.20.0.25 (3b53e529b)

2 years ago I have the same problem. The app crashes while debugging, but works fine when just running it. Disabling the mono interpreter now allows me to debug, but hot reload no longer works.
@whitneyschmidt @dalexsoto @rolfbjarne if you guys want to reproduce the issue, then include a native C library in xamarin ios project (libX,iOS.a) and then call one of its functions (P/Invoke) using System.Runtime.InteropServices, e.g.:
[DllImport("__Internal", EntryPoint = "interpret_scan_data_buffer")] public static extern int DeserialiseScanDataIos(byte[] buffer, int bufferSize, ref NativeScanData scanData);
Seems like I can either use hot reload, or call native C functions, but not both.

I have a few dynamic type resolves in my code and disabling this is not an option for me (since iOS doesn't support JIT)

1 year ago The problem still persists, just the line number has changed. The error is now:
error: * Assertion at /Users/builder/jenkins/workspace/archive-mono/2020-02/ios/release/mono/mini/mini-arm64.c:5447, condition `native_offset % 4 == 0' not met
My breakpoint is in a XF solution in the iOS project.
The app crashes when the breakpoint is hit.
This is VS2022, version 17.7.0 Preview 2.0 on Windows and 17.6 Preview (Build 1539) and Xamarin.iOS 16.4.0.5 on the Mac.
Maybe the issue text should be "App crashes when resolving a breakpoint" instead.
When I disable the Mono Interpreter, then it works.
MichaelRumpler
commented
1 year ago Are we really still running on a Mono version from 2020 like the path suggests? Cause in the current version that assert is in line 5491 and the file mini-arm64.c was last changed two years ago. Why isn't that updated?

From @Tragetaschen on Tue, 02 Jun 2020 14:10:49 GMT
Steps to Reproduce
I have a couple of view model constructors where, when I set a break point on the line with the closing curly brace, the process on the iPhone hits an assertion and crashes. So far, I have not identified anything special about the constructor or last instruction—for example, there is one that just sets five
ICommandproperties. Some break points on the closing brace trigger it, some don't.Expected Behavior
No crash
Actual Behavior
Environment
