            Bug ID: 254248
           Summary: REGRESSION(261825 at main?): [ JSC ] 4X Test262-Tests are
                    constant failures in default and strict mode
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: Jenner at apple.com

The following 4x test-262-tests are constant failures in default and strict mode on macOS Monterey+:

test/built-ins/Function/prototype/bind/instance-length-default-value.js
test/intl402/Collator/prototype/compare/compare-function-name.js
test/intl402/DateTimeFormat/prototype/format/format-function-name.js
test/intl402/NumberFormat/prototype/format/format-function-name.js

HISTORY:
https://build.webkit.org/#/builders/760

Looking at the test runs there appears to be a pretty clear regression point of 261825 at main. That's when the tests started to fail, and it appears that the macOS version, Xcode version, and the timezone database version were all the same between 261825 at main, the first observed failure and 261824 at main, the last time everything was passing.
