            Bug ID: 144347
           Summary: Use the default hash value for Symbolized StringImpl
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: utatane.tea at gmail.com

Currently, symbolized StringImpl* has a special hash value to avoid the hash collision with the other normal StringImpl*. (Maybe it is introduced when private symbols are introduced)
However, it prevents using symbolized StringImpl* in the other place (such as using it as WTFString cause a problem because of its special hash value).

I think this situation leads a serious error easily.
To avoid this, I propose using the usual hash value in symbolized StringImpl*.
And if collision is a problem, I suggest introducing a special Hasher for PropertyTable.
