            Bug ID: 206572
           Summary: KeyedDecoderGeneric crashes when it accesses a data
                    with empty string key.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: Takashi.Komori at sony.com

When KeyedDecoderGeneric decodes a record associated with empty string key, it tries to add a record to a HashMap with null string (not empty string) but adding HashMap fails because HashMap can't treat null string as a key.

While adding a record with null string key, StringHash::hash() crashes by accessing null pointer.
