 This is reproducible with MCS too.  If I move the 'object[] instrs'
 line below the anonymous delegate, it works again.  That suggests to
 me that somewhere, the code isn't handling implicit blocks.

+Just to track the problem.
+
+This is a simpler program:
+
+public class Test1 {
+  public static void Main() {
+    int a // = 1;
+    check_t m = delegate () {
+        m ();
+    };
+  }
+
+  delegate void check_t();
+}
+
+The above compiles, if we remove the // from that program it will fail.
+
+The problem is in the lookup process for locals, currently we have
+linked two TopLevelBlocks like this:
+
+Delegate.TopLevelBlock.Parent = Main.TopLevelBlock
+
+But it should be:
+
+Delegate.ToplevelBlock.Parent = Main.ToplevelBlock.FirstDeclaration
+
+With IDs:
+
+1 public class Test1 {
+2  public static void Main() {
+3    int a = 1;
+4    check_t m = delegate () {
+5        m ();
+6    };
+7  }
+
+2: the first toplevel block
+3: implicit block created for the assignemtn of 1 to a.
+4: second toplevel block, with its parent pointing to `2'
+
+Have not found where the linking gets messed up yet.
