[Insight-developers] Help to debug on LInux64 and Mac 10.5

[Bill Lorensen]

OK, the 64 bit output shows that for (0, 0, 1) there are two different has
codes generated.
The codes differ after the first time the hash overflows.
...
hash before: 1075801880
p now      : 63
hash after : 1207645527
hash before: 1207645527
p now      : 4
hash after : 1187547931

...
hash before: 1075801880
p now      : 63
hash after : 1207645527
hash before: 1207645527
p now      : -1
hash after : 1187547926

This shows that the overflow has two different results.
