+Summary: need to consider interfaces that implement interfaces at type creation
+
+When a type implements an interface that itself implements (or derives, or
+whatever the correct term is in that case), all the interfaces need to be
+added to the type or you'll get a type load error.
+The test below was extracted from the real case that happens in system.dll.
+Compile and PEVerify the binary.
+interface A {
+ void stuff ();
+}
+interface B: A {
+ void stuff2 ();
+}
+class T: B {
+ public void stuff () {}
+ public void stuff2 () {}
+ static void Main() {}
+}
+
+If you try to run the binary you also get a better (if a little confusing)
+error message.
+If you check with monodis --interface, you'll note that T is recorded to
+implement only B, while it implements A, too.
+The bug happens with either runtime.
