+	    QuoRem, Mod, ModInverse, ModSqrt, Jacobi, and GCD) can panic
+	    when provided crafted large inputs. For the panic to happen,
+	    the divisor or modulo argument must be larger than 3168 bits
+	    (on 32-bit architectures) or 6336 bits (on 64-bit architectures).
+	    Multiple math/big.Rat methods are similarly affected.</p>
