           Summary: HashTable internal index is not always deleted
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fmarmond at pleyo.com


HashTable::createTable() allocates new HashEntry array, but
HashTable::deleteTable() is not always called, so this array may not be
deleted.

It can then introduce memory leaks, valgrind gives one of around 800ko on a
single gmail visit.

My fix is to call the deleteTable() in the HashTable destructor.
It is secured and fixes the memory leak.
