Nicolas Cellier uploaded a new version of Kernel to project The Trunk: http://source.squeak.org/trunk/Kernel-nice.1332.mcz

Name: Kernel-nice.1332 Author: nice Time: 25 June 2020, 1:40:53.258508 am UUID: 1a712e0e-296b-394e-ad45-7374959e1d30 Ancestors: Kernel-tonyg.1331
Fix the bug found in Cuis by Luciano Notarfrancesco and resolved by Juan Vuletich
i:=0. [a := (1 << 60) atRandom. b := (a bitReverse: 64) bitReverse: 64. a = b] whileTrue:[i:=i+1]. ^i
Above loop should not stop. But unnormalized Integer were sometimes returned,
