+Summary: Multidimensional array as generic paramater causes gmcs to crash
+
+Description of Problem: Using int[,] as a type parameter for a generic type
+crashes gmcs
+
+
+Steps to reproduce the problem:
+1.
+cat > test.cs << EOF
+class B {
+  System.Collections.Generic.List<int[,]> x;
+
+  static void Main() {}
+}
+EOF
+2. gmcs test.cs
+
+Actual Results:
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+in <0x00000> <unknown method>
+in (wrapper managed-to-native) System.Type:BindGenericParameters

+
+
+Expected Results:
+The code should compile.
+
+How often does this happen? 
+Always
+
+Additional Information:
+The same error appears with the nemerle compiler, so the bug is probably in
+System.Reflection.Emit.
+
+I'm using Mono svn r48453.
