           Summary: REGRESSION (r51670-51675): Two fast/js tests are
                    crashing on Windows
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://build.webkit.org/results/Windows%20Release%20(T
                    ests)/r51675%20(6688)/results.html
        OS/Version: Windows XP
            Status: NEW
          Keywords: LayoutTestFailure, NeedsRadar, PlatformOnly
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: aroben at apple.com

To reproduce:

1. run-webkit-tests

Two fast/js tests crash: fast/js/excessive-comma-usage.html and
fast/js/math-transforms.html. See
<http://build.webkit.org/results/Windows%20Release%20(Tests)/r51675%20(6688)/results.html>
for an example of the crashes.

This started happening between r51670 and r51675. The new "rope" JS string
representation landed in this range, and seems likely to be the culprit.
