Internal Compiler Error when Accessing Struct Property #1538
Description
Describe the bug
There seems to be a bug in the ILGPU compiler.
I have reduced my code to the following minimal example. The given unit test fails with the message: "An internal compiler error has been detected in method Void KernelMethod(ParameterLayer1)". Most changes in the remaining code let the unit test succeed; apparently the problem lies in the somewhat complex nature of the code.
using ILGPU; using ILGPU.Runtime; public sealed class FactsClass { [Fact] public void This_unit_test_fails() { var context = Context.Create(builder => builder.AllAccelerators()); var device = context.GetPreferredDevice(false); var accelerator = device.CreateAccelerator(context); var loadedKernel = accelerator.LoadStreamKernel<ParameterLayer1>(KernelMethod); } private static void KernelMethod(ParameterLayer1 p) { var v = DataLayer1.StaticMemberStruct.A; } private readonly record struct ParameterLayer1(ParameterLayer2 p2); private readonly record struct ParameterLayer2(ParameterLayer3 p3); private readonly record struct ParameterLayer3(ParameterLayer4 p4); private readonly record struct ParameterLayer4(float a, TestVector b); private readonly struct DataLayer1 { public static DataLayer2 StaticMemberStruct { get; } = new(new TestVector(float.MaxValue, float.MaxValue, float.MaxValue), float.MaxValue); } private readonly struct DataLayer2(TestVector a, float b) { public readonly TestVector A = a; public readonly float B = b; } private readonly record struct TestVector(float X, float Y, float Z); } Environment

- .NET version: .NET 9
- Operating system: Windows 11
- Hardware: AMD Ryzen 9
