https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258762 Bug ID: 258762 Summary: www/chromium: Serious typed array initialization problem 92.0.4515.159 (Official Build) (64-bit) Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: Individual Port(s) Assignee: chromium@FreeBSD.org Reporter: jschachter@spendata.com Assignee: chromium@FreeBSD.org Flags: maintainer-feedback?(chromium@FreeBSD.org) Created attachment 228233 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D228233&action= =3Dedit HTML file with javascrpt that reproduces the bug Typed arrays are being initialized filled with garbage, not zeros. 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.=
