For example: var r =3D new Int32Array(38); r Int32Array(38)=C2=A0[-399179776, -1610579712, 399179775, 1610579711, 0, 0, = 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, = 0, 0, 0, 0] See attached html file with javascript within for a test case. To reproduce the bug, open Chromium, then open devtools. Load the attached HTML page. It will give you instructions, which boil down to executing the above two commands, then refreshing the page and repeating until you find t= hat the array "r" was initialized with garbage. This is a show-stopping bug: My company's complex javascript application completely fails to run because its data arrays get corrupted as above. --=20 You are receiving this mail because: You are the assignee for the bug.=
