--- Comment #3 from Stéphane MOTTELET <stephane.mottelet at utc.fr> ---
Sorry, it is worse than that: under Windows there is a bug of exponentiation and multiplication for uint64 (addition seems ok):

Windows :
--> x = [ uint64(2)^63+uint64(2)^63, 2*uint64(2)^63, uint64(2)^64 ]
 x  = 

  0  9223372036854775808  9223372036854775808


--> x==0
 ans  =

  T F F

OSX, Linux:
-->  x = [ uint64(2)^63+uint64(2)^63, 2*uint64(2)^63, uint64(2)^64 ]
 x  = 

  0  0  0


--> x==0
 ans  =

T T T
