Similar to #76551, gmcs misses class constraints on abstract/overriden methods:

using System;
using System.Reflection;

public abstract class Foo<T> where T : class
{
        public abstract Foo<K> UseT<K> () where K : class;
}

public class Bar<T> : Foo<T> where T : class
{
        public override Foo<K> UseT<K> () { return default (Foo<K>); }
}

public class Test
{
        public static void Main ()
        {
                MethodInfo mi = typeof (Bar<object>)
                        .GetGenericTypeDefinition ().GetMethod ("UseT");
                foreach (Type t in mi.GetGenericArguments ())
                        Console.WriteLine (":::{0} {1}",
                                t, t.GenericParameterAttributes);
        }
}

Compile with gmcs and run either on MS.NET or Mono.

Actual Results:

:::K None

Expected Results:

:::K ReferenceTypeConstraint

How often does this happen? 

consistently.

Should be easy.
