+Subject: Clobber nil bug and Tail recursion bug
+
+BUG 2
+    When compiling Ackerman for the vax it tries to remove the
+tail recursion. However the tail recursive call contains another
+call so the update (used to be parameter passing) can't be done
+until the imbedded call returns.
+
+SOURCE
+
+/* Ackerman's function */
+main()
+{
+	int i;
+
+	i = A(3,6);
+	if (i == 509)
+		printf("Test passed\n");
+	else
+		printf("FAILED ackerman's(3, 6): %d\n", i);
+}
+
+A(x,y)
+int x,y;
+{
+    if(x==0) return(++y);
+    if(y==0) return(A(--x,1));
+    return(A(x-1,A(x,--y)));
+    }
