+Summary: FieldInfo.GetValue causes runtime exception 
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+FieldInfo.GetValue causes runtime exception 
+
+Steps to reproduce the problem:
+1. extract Tao assemblies from http://nemerle.org/~nazgul/temp/tao.tar.gz
+
+2. Compile and run following program (mcs t.cs /r:Tao.OpenGl.dll)
+
+class M {
+static void Main () {
+
+System.Type x = typeof (Tao.OpenGl.Gl);
+System.Reflection.FieldInfo f = x.GetField ("GL_TEXTURE_2D");
+System.Console.WriteLine ("{0}", f);
+System.Console.WriteLine ("{0}", f.GetValue (null));
+
+}
+}
+
+3. Run it
+
+Actual Results:
+=================================================================
+Got a SIGSEGV while executing native code. This usually indicates
+a fatal error in the mono runtime or one of the native libraries 
+used by your application.
+=================================================================
+
+Stacktrace:
+
+in (wrapper managed-to-native) System.Reflection.MonoField:GetValueInternal
+(object) <0x4>

+        /home/users/nemweb/local/bin/mono [0x808f352]
+        [0xffffffff]
+Aborted
+
+
+Expected Results:
+System.Int32 GL_TEXTURE_2D
+3553
+
+
+How often does this happen? 
+With recent svn always, it seems like a regression from a few days ago
+
+Additional Information:
+it works with earlier versions of mono
