+Summary: "unknown type 0x13" on --aot compilation of generics
+Description of Problem:
+mono --aot crashes on certain methods using generics.
+Steps to reproduce the problem:
+1. `gmcs /target:library foo.cs`, the contents being:
+class SimpleIterator<T>: System.Collections.IEnumerator
+  T x;
+  public void Reset(){}
+  public bool MoveNext() {return false;}
+  public object Current {
+    get { return x; }
+  }
+2. mono --aot foo.dll
+Actual Results:
+Mono Ahead of Time compiler - compiling assembly /tmp/foo.dll
+** ERROR **: unknown type 0x13 in type_to_ldind
+Expected Results:
+How often does this happen? 
+Additional information:
+The behavior doesn't change if compiled into an .exe assembly with a dummy
+main method. Code that crashes AOT compilation can be executed JIT without
+a problem.
