Steps to Reproduce

(this seems to be a net8 regression, here's my attempt to get close to isolating the specific trigger/s for the issue through trial and error)

  1. Be using .net8 preview, running release builds on a physical device
  2. In c#, define an 'NSObject' subclass that wraps a .net type T and stashes the T instance and a Func<T,?> "identifier-getter" that is called against the wrapped instance whenever objc triggers GetNativeHash
  3. Instantiate wrapper in a specific problematic way over specific problematic types (this I determine from experimentation, see sample project)
  4. Use the wrapper instance in a way that will cause GetNativeHash to be triggered from native code.

Expected Behavior

The wrapper instance can be used with native types in expected ways without issues, as when run under net7 on device, or under net8 on simulator (/debug??) builds.

Actual Behavior

Build Logs

Example Project

https://github.com/rdavisau/ios-net8-funchash-repro

Run on net7 (works)
./net7.sh [DEVICE UDID]

Run on net8 (crashes)
./net8.sh [DEVICE UDID]

All relevant code is in AppDelegate.cs. The commented out instantiations (1 - 4) all work on both net7 and net8. The final instantiation causes the crash when the NSSet is being created.

This has easy workarounds (use the 'not problematic' instantiation, or calculate and stash the identifier in the constructor), but since it 'used to work' in net7 I figure it is worth raising.

I can reproduce the crash.

It only happens when LLVM is enabled.

lldb session on device: https://gist.github.com/rolfbjarne/bb24af32b545371d4ff314391e6abd6f

Output without lldb: https://gist.github.com/rolfbjarne/dc0ec66a78140d49c523eecf81705a19

I have a few local changes to make it clearer that the crash happens when calling GetHashCode: https://gist.github.com/rolfbjarne/e3bdaaba00fe0e55d7c74b27e0a75242

I build like this:

dotnet build FuncHash.csproj /p:RuntimeIdentifier=ios-arm64

I'm moving to dotnet/runtime since this seems like a regression with our LLVM support.

It only happens when LLVM is enabled.

This might be an incorrect conclusion, because I didn't see that the test project does this:

@vargaz that's weird. Can you get a binlog?

Attached.

The first is from:

And the second is from:

I guess these all produce debug builds, but for me the issue only reproduces on a release build.

For me, this crashes:
rm -rf bin obj && dotnet restore FuncHash.csproj && dotnet run -v:n --project FuncHash.csproj -f net8.0-ios -c Release -r:ios-arm64 /p:_DeviceName=

This doesn't (removed -c Release):
rm -rf bin obj && dotnet restore FuncHash.csproj && dotnet run -v:n --project FuncHash.csproj -f net8.0-ios -r:ios-arm64 /p:_DeviceName=

I can reproduce in release config.

A reduced testcase:

using System;
using System.Runtime.CompilerServices;

namespace FuncHash;

[Register ("AppDelegate")]
public class AppDelegate : UIApplicationDelegate
{
	public override UIWindow? Window { get; set; }

	public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
	{
		Window = new UIWindow { RootViewController = new UIViewController { View = { BackgroundColor = UIColor.Green } }};
		Window.MakeKeyAndVisible();

		var t = typeof (Identifier<,>).MakeGenericType (new Type [] { typeof (int), typeof (string) });
		var a = Activator.CreateInstance (t, new object [] { delegate () { return "2"; } });
		return true;
	}
}

public class Identifier<T,U>
{
	public Identifier(Func<U> identifierFunc)
	{
		Console.WriteLine ("B: " + identifierFunc());
	}
}

[mono][jit] Avoid doing copy propagation on ldaddr for gsharedvt vari…
c2da413 
…ables.

Ldaddr requires the emission of dummy uses for
gsharedvt_info_var/gsharedvt_locals_var and the copy wouldn't have these,
leading to register allocation problems.

Fixes dotnet#87551.
