Bug ID: 170537
Summary: test262: REGRESSION(r207226):
test262/test/built-ins/Array/prototype/splice/create-p
roxy.js.default-strict: Exception: TypeError:
Attempted to assign to readonly property.
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org

A few test262 tests fail after:
<https://webkit.org/b/163338> Array.prototype.slice should not modify frozen objects
<http://trac.webkit.org/r207226>
Steps to Reproduce:
1. Check JSTests/test262.yaml expectations for the above file paths (if they are marked as :fail)
2. $ run-jsc-stress-tests JSTests/test262.yaml
Notes:
- Not sure if these are progressions, but since the tests themselves don't seem to mention freezing anything it seems unexpected.
- If this is an actual failure the expectations can be changed to :failDueToOutdatedOrBadTest
