+Summary: Compiler crashes processing MarshalAs
+
+Description of Problem:
+Compiler "crashes" when compiling a program containing
+[MarshalAs(UnmanagedType.ByValArray, SizeParamIndex=2)] within a function
+prototype.
+
+Test Case:
+
+using System;
+using System.Text;
+using System.Runtime.InteropServices;
+
+public class main {
+
+                [DllImport("libname", EntryPoint = "scumbag")]
+                private unsafe static extern int scumbag(ref int X,
+                [MarshalAs(UnmanagedType.ByValArray, SizeParamIndex=2)] ref
+byte[] fb,
+                long  lFb,
+                [MarshalAs(UnmanagedType.ByValArray, SizeParamIndex=4)] ref
+byte[] rb,
+                long  lRb,
+                [MarshalAs(UnmanagedType.ByValArray, SizeParamIndex=6)] ref
+byte[] sb,
+                long  lSb,
+                [MarshalAs(UnmanagedType.ByValArray, SizeParamIndex=8)] ref
+byte[] vb,
+                long  lVb,
+                [MarshalAs(UnmanagedType.ByValArray, SizeParamIndex=10)]
+ref byte[] ib,
+                long  lIb);
+
+        static void Main() {
+                int rc;
+                Console.WriteLine("Waiting..");
+                string line = Console.ReadLine();
+        }
+
+}
+
+Test Results:
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
