+Summary: compiler crash when property name matches privatescope field name
+
+Given the library assembly:
+
+.assembly extern mscorlib {}
+.assembly TestLib {}
+.module TestLib.dll
+.imagebase 0x00400000
+.subsystem 0x00000003
+.file alignment 512
+.corflags 0x00000001
+
+.class public auto ansi beforefieldinit TestLib
+       extends [mscorlib]System.Object
+{
+  .field static privatescope int32 FOO
+
+  .method public hidebysig specialname static int32
+          get_FOO() cil managed
+  {
+    ldsfld      int32 TestLib::FOO
+    ret
+  }
+
+  .property int32 FOO()
+  {
+    .get int32 TestLib::get_FOO()
+  }
+}
+
+And the C# application:
+
+public class Test
+{
+   public static void Main()
+   {
+      System.Console.WriteLine(TestLib.FOO);
+   }
+}
+
+When you compile the C# application with mcs you get an exception:
+
+C:\mcsbug>mcs test.cs -r:testlib.dll
+Exception caught by the compiler while compiling:
+   Block that caused the problem begin at: test.cs(3,23):
+                     Block being compiled: [test.cs(4,4):,test.cs(6,4):]
