           Summary: REGRESSION (r39337): jsfunfuzz generates identical test
                    files
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: oliver at apple.com

jsfunfuzz uses Math.random() to generate random test resutls.  Prior to
squirrelfish it generated different results for every test file.  Now the files
are all identical

12/29/08 5:59 PM Oliver Hunt:
The unification of the random number generation in r39337 made random number
generation always start with the same seed in JSC.  This is non-standard
behaviour based on both our old behaviour and that of other browsers.
