+Summary: Compiler crash on error.
+
+The compiler crashes when compiling this buggy program:
+
+using System;
+
+namespace System.Web.Configuration
+{
+	class MachineKeyConfig
+	{
+		static MachineKeyConfig ()
+		{
+			autogenerated = new byte [64];
+			RNGCryptoServiceProvider cp = new RNGCryptoServiceProvider ();
+			cp.GetBytes (autogenerated);
+		}
+	}
+}
+
+It produces:
+/tmp/aa.cs(11) error CS0246: The type or namespace name
+`RNGCryptoServiceProvider' could not be found. Are you missing a using
+directive or an assembly reference?
+/tmp/aa.cs(10) error CS0246: The type or namespace name `autogenerated'
+could not be found. Are you missing a using directive or an assembly reference?
+/tmp/aa.cs(10) error CS0103: The name `autogenerated' does not exist in the
+context of `System.Web.Configuration.MachineKeyConfig'
+/tmp/aa.cs(11) error CS0246: The type or namespace name
+`RNGCryptoServiceProvider' could not be found. Are you missing a using
+directive or an assembly reference?
+Exception caught by the compiler while compiling:
