+Summary: [GMCS] (cf. #76551) missing "class" constraints on abstract generic method IL
+
+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.
