+Summary: trying to ldftn a dynamicmethod crashes the runtime
+
+Trying to use ldftn opcode to a DynamicMethod crashes the runtime:
+
+DynamicMethod method = new DynamicMethod("func", typeof(void), new Type[0],
+typeof(Program));
+ILGenerator ilgen = method.GetILGenerator();
+ilgen.Emit(OpCodes.Ldftn, method);
+ilgen.Emit(OpCodes.Pop);
+ilgen.Emit(OpCodes.Ret);
+method.Invoke(null, new object[0]);
+
+** ERROR **: file reflection.c: line 9783 (resolve_object): assertion
+failed: (method->mhandle)
+aborting...
+
+MS CLR refuses to emit that IL code, throwing an exception: Ldtoken, Ldftn
+and Ldvirtftn OpCodes cannot target DynamicMethods.
