+Summary: [GMCS] CS0121 - a call is ambiguous between the base class and generic derived class
+
+The example code below fails to compile because of incorrectly computed
+ambiguity:
+
+using System;
+
+class DerivedGenericClass<T> : BaseClass // this <T> causes the bug
+{
+        public override void Foo () {}
+
+        public void Baz ()
+        {
+                Foo ();
+        }
+}
+
+abstract class BaseClass
+{
+        public abstract void Foo ();
+}
+
+
+Actual Results:
+
+foo.cs(9,3): error CS0121: The call is ambiguous between the following
+methods o
+r properties: `BaseClass.Foo()' and `DerivedGenericClass<T>.Foo()'
+foo.cs(15,23):: `BaseClass.Foo()', name of symbol related to previous error
+foo.cs(5,23):: `DerivedGenericClass<T>.Foo()', name of symbol related to
+previou
+s error
+Compilation failed: 1 error(s), 0 warnings
+
+Expected Results:
+
+no error other than CS5001 (entrypoint not found).
+
+How often does this happen? 
+
+consistently.
