A Mono program crashes when a static virtual method is called on an interface but only in the Debug configuration.
The same program works correctly with CoreCLR or with Mono in the Release configuration. I observed this while working on xamarin-macios (see xamarin/xamarin-macios#18519 (comment)).

Reproduction steps

To reproduce the issue, put the following code to the HelloWorld sample code in src/mono/sample/HelloWorld/Program.cs:

using System;

Console.WriteLine(CallMyMethod<MyClass>());
Console.WriteLine(CallMyMethod<IMyInterface>());

string CallMyMethod<T>() where T : IMyInterface
    => T.MyMethod();

interface IMyInterface {
    static virtual string MyMethod() => nameof(IMyInterface);
}

class MyClass : IMyInterface {
    public static string MyMethod() => nameof(MyClass);
}

Run the program via make -C src/mono/sample/HelloWorld run.

Instead of printing both lines, program crashes:

MyClass
* Assertion at /.../dotnet/runtime/src/mono/mono/mini/mini-generic-sharing.c:2289, condition `m_class_get_vtable (info->klass)' not met
