Build and run this with gshared JIT:

namespace Gin {
    public interface I {
	static abstract void Foo<T>(T x);
    }

    public class C : I {
	public static void Foo<T>(T x) {
	    Console.WriteLine (x.GetType());
	}
    }

    public class G<U> where U : I {
	public void Caller<T> (T x) {
	    U.Foo(x);
	}
    }
}

namespace HelloWorld
{
    internal class Program
    {
        private static void Main(string[] args)
        {
	    var g = new Gin.G<Gin.C>();
	    g.Caller("123");
        }
    }
}

Expected result:

System.String

Actual result:

* Assertion at /Users/alklig/work/dotnet-runtime/runtime-bugs/src/mono/mono/mini/method-to-ir.c:6294, condition `!sig->has_type_parameters' not met
