HTML file with javascrpt that reproduces the bug

Typed arrays are being initialized filled with garbage, not zeros.

For example:

var r = new Int32Array(38);
r
Int32Array(38) [-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 that
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.
