+Summary: Unhandled exception when trying to set a internal get-only property
+
+Hi,
+
+when doing the following mcs crashes with an unhandled exception:
+
+mcs -out:test.dll -target:library test2.cs
+mcs -out:test.exe test.cs -r:test.dll
+
+Exception caught by the compiler while compiling:
+   Block that caused the problem begin at: test.cs(5,21):

+
+this is with mono 1.1.13.4 and happens always. When setting the property to
+public the correct error (get-only property, CS0200) is printed by mcs. The
+same correct behaviour happens when compiling both files in one assembly.
+Below are the two test files.
+
+
+
+test.cs:
+-----------------
+using System;
+public class Test : Foo {
+
+	public static void Main(string[] args) {
+		Test = false;
+	}
+}
+-----------------
+
+test2.cs:
+-----------------
+using System;
+public class Foo {
+	internal static bool Test {
+		get { return true; }
+	}
+}
+-----------------
