+Summary: CS0535 is not reported when base class explicitly implements interface with same members
+
+When interfaces share the same member signature, and a certain class (B) 
+implements an interface (ITest2) while its base class (A) explicitly 
+implements another interface (ITest1) with the same member signature, 
+then mcs does not report CS0535 if the derived class does not actually 
+provide an implementation for the interface it implements (ITest2).
+
+To reproduce this issue, compile the following code snippet (using 
+mcs /target:library):
+
+public interface ITest1 {
+	void GetName(string id);
+}
+
+public interface ITest2 {
+	void GetName(string id);
+}
+
+public class A : ITest1 {
+	void ITest1.GetName(string id) {
+	}
+}
+
+public class B : A, ITest2 {
+}
+
+Actual result:
+
+Successful compilation.
+
+Expected result:
+
+test.cs(14,14): error CS0535: 'B' does not implement interface 
+member 'ITest2.GetName(string)'
+test.cs(6,7): (Location of symbol related to previous error)
