If XAML contains code that sets a property of the GridLength? type, the release build is failed.

• Android: Error: Microsoft.Android.Sdk.Aot.targets(110,5): error : Precompiling failed for DXMauiApp.dll with exit code 139.
  *iOS: Error: Xamarin.Shared.Sdk.targets(1279,3): error : Failed to AOT compile DXMauiApp.dll, the AOT compiler exited with code 139.

Steps to Reproduce

1. Download the reproduction repository
2. Try to build the project in the Release configuration

Expected outcome: build successful
Actual outcome: error with exit code 139.

@jonathanpeppers @rolfbjarne thoughts?

[jonathanpeppers]

mono-aot-cross just has an exit code with no error message:

[DXMauiApp.dll] Running: C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Runtime.AOT.win-x64.Cross.android-x64\9.0.0\Sdk\..\tools\mono-aot-cross.exe --response="C:\Users\maleib\AppData\Local\Temp\tmpklrmaw.tmp"
...
[DXMauiApp.dll] Exit code: -1073741819

@mattleibow do you still have DXMauiApp.dll on disk? We can run ilverify on it to see if it is valid.

But we can probably pass this to dotnet/runtime for them to take a look.

[jonathanpeppers]

After inspecting the IL, we think the Xaml compiler is doing something incorrect for a nullable GridLength?.

Moving back to MAUI.
