+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:
+cat > test.cs << EOF
+class B {
+  System.Collections.Generic.List<int[,]> x;
+  static void Main() {}
+2. gmcs test.cs
+Actual Results:
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+in <0x00000> <unknown method>

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