+Summary: Problem compiling recursive delegates
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+Inconsistent C# compiler behavior (gmcs).
+
+Steps to reproduce the problem:
+
+This program compiles with no warnings:
+
+public class Test1 {
+  public static void Main(string[] args) {
+    check_t check = delegate (object[] instrs, int MC) {
+      if (MC < instrs.Length) {
+        object instr = instrs[MC];
+        System.Console.WriteLine("Hello world: {0}", instr);
+        check(instrs, MC + 1);
+      }
+    };
+    check(new object[]{"foo", "bar"}, 0);
+  }
+
+  delegate void check_t(object[] instrs, int MC);
+}
+
+This equivalent program does not compile:
+
+public class Test2 {
+  public static void Main(string[] args) {
+    // the following line is the only change
+    object[] instrs = new object[]{"one", "two"};
+    check_t check = delegate (object[] instrs, int MC) {
+      if (MC < instrs.Length) {
+        object instr = instrs[MC];
+        System.Console.WriteLine("Hello world: {0}", instr);
+        check(instrs, MC + 1);
+      }
+    };
+    check(new object[]{"foo", "bar"}, 0);
+  }
+
+  delegate void check_t(object[] instrs, int MC);
+}
+
+Actual Results:
+
+$ gmcs Test2.cs
+Test2.cs(9) error CS0103: The name `check' could not be found in `Test2'
+Compilation failed: 1 error(s), 0 warnings
