+Summary: mini bug with deadce and method calls
+
+The following test is compiled wrong with mini when the deadce optimization
+is enabled:
+class testObject {
+  public virtual int dothis(int iter) {
+    return iter;
+  }
+    public static void object_test(int INDEX) {
+      int y;
+      testObject obj = new testObject();
+
+      for (int x=0;x<INDEX;x++) {
+         y = obj.dothis(10);
+      }
+    }
+
+    static void Main () {
+	    object_test (5000000);
+    }
+}
+
+Inside the loop the call and the assignment to y is removed, but a push of
+the argument of the function is left and if the number of iterations is
+large, you get a stack overflow.
