           Summary: REGRESSION (r35531-r35615) Acid3 crashes on Windows with
                    Safari 3.1 + WebKit Nightlies
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
               URL: http://acid3.acidtests.org/
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Critical
          Priority: P1
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mhstamate at yahoo.com


Tested on:
- Windows XP SP2
- Apple Safari for Windows 3.1.2 using a WebKit nightly build for Windows from
http://nightly.webkit.org/
- Intel P4 2.4 GHz CPU (single core)
- javascript is enabled

How often it happens: always

Description:
1. using any nightly WebKit build from nightly.webkit.org after build r35531
(the first one avaliable on that website is r35615)
2. go to http://acid3.acidtests.org/ to take the Acid3 test
3. the test runs, it displays 74/100 and then the web browser crashes


The last WebKit nightly build for Windows on nightly.webkit.org that doesn't
crash is r35531.
The next WebKit nightly build for Windows on nightly.webkit.org is r35615, and
it does crash. Every WebKit nightly build following r35531 that was tested
caused a crash (r35615, 35641, 35648).
So, the change that caused the hang must have happened somewhere in between
builds r35531 and r35615 (for Windows).
