Static [InlineArray] of self type crashes when loading type

[bruce965]

Description

A struct containing a static [InlineArray] of itself always crashes at runtime.

Reproduction Steps

In a new console project, paste this code.

using System;
using System.Runtime.CompilerServices;

Hello a;

[InlineArray(1)]
struct HelloBuffer
{
    Hello _v;
}

struct Hello
{
    static HelloBuffer s_buffer;

    int _v;
}

Expected behavior

Should compile and run, without producing any output.

Actual behavior

Compiles, but crashes at runtime.

Unhandled exception. System.TypeLoadException: Could not load type 'Hello' from assembly 'a, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
   at Program.<Main>$(String[] args)

Regression?

No response

Known Workarounds

Just place the buffer in a separate class.

using System;
using System.Runtime.CompilerServices;

Hello a;

[InlineArray(1)]
struct HelloBuffer
{
    Hello _v;
}

static class HelloBufferHelper
{
    static HelloBuffer s_buffer;
}

struct Hello
{
    int _v;
}

Configuration

.NET 9.0.203

Linux 6.15.9-106.bazzite.fc42.x86_64 #1 SMP PREEMPT_DYNAMIC Sat Aug 9 13:06:19 UTC 2025 x86_64 GNU/Linux

I haven't tested on different platforms, architectures, .NET versions, and configurations.

I'm a bot. Here are possible related and/or duplicate issues (I may be wrong):

• System.TypeLoadException When Interface Type Contains Static Field/Property for Derived Struct Type #104511
• TypeLoadException when using a struct containing a static ImmutableArray<T> field/auto-property #100077
• static ImmutableArray field causing TypeLoadException on structs #118309

Presumably it is fixed by #118413:
