 Multiplication of two integers around 32 bits in length can lead to what
 appears to be a buffer overflow and incorrect results:

 For example:

 {{{
 irb(main):001:0> ((2**32)-(2**29))*(2**32)
 => -2305843009213693952
 irb(main):002:0> (2**32)*(2**32)
 => 0
 irb(main):003:0> (2**32)*(2**32+2**31)
 => 27670116110564327424
 }}}

 Both of these are
