+Summary: Foreach on Array should throw InvalidCastException but does not
+
+Description of Problem:
+
+Foreach on jagged Array should throw InvalidCastException but does not.
+
+Steps to reproduce the problem:
+1. Compile and run the program below
+
+using System;
+
+class TestArray {
+  public static void Main(String[] args) {
+    double[] zero1 = { 1.0 };
+    double[] zero2 = { 2.0, 3.0 };
+    double[][] t2 = { zero1, zero2 };
+    Array a = t2;
+
+    foreach (double d in a)
+      Console.Write(d + " ");
+    Console.WriteLine();
+  }
+}
+
+Actual Results:
+
+2.12199579096527e-314 4.24399158193054e-314
+
+Expected Results:
+
+InvalidCastException
+
+How often does this happen? 
+
+Always on Debian Linux mono 0.23.
+
+
+Additional Information:
+
+The mcs-generated bytecode behaves correctly under MS CLR 1.1 so the C#
+compiler is not to blame.
