-	 * XXX - is this still an issue?

-	 * Saber-C Version 3.1 says:
-	 *
-	 *    W#26, Storing a bad pointer into auto variable dmul`baseC.
-	 *
-	 * This warning is issued during the regression test #026
-	 * (read cryrand).
-	 *
-	 * Saver-C claims that v2+shift is past the end of allocated
-	 * memory for v2.
-	 *
-	 * This warning may be triggered by executing the following code:
-	 *
-	 *	a = 0xffff0000ffffffff00000000ffff0000000000000000ffff;
-	 *	config("mul2", 2);
-	 *	pmod(3,a-1,a);
-	 *
-	 *	[[ NOTE: The above code no longer invokes this code. ]]
-	 *
-	 * When this code is executed, shift == 6 and v2 is 3 shorts
-	 * long (size2 == 2).  This baseC points 3 shorts beyond the
-	 * allocated end of v2.
-	 *
-	 * The stack was as follows:   [[NOTE: line numbers may have changed]]
