           Summary: Freezing a function and its prototype causes browser
                    to crash.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: erights at gmail.com


On Version 5.0.5 (5533.21.1, r87697), in a squarefree shell (but consistent with other behavior I've seen), I type in:

function foo(){}
Object.freeze(foo);
Object.freeze(foo.prototype);

I then get a beach ball for a short while only over that Safari, and then that Safari crashes. For the sake of isolating this, I tried rebooting and launching a fresh Safari. Same symptoms.
