           Summary: Uninitialized member being used before set
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: dacarson at gmail.com

In kjs/property_map.cpp
In PropertyMap::mark()

  Entry *entries = _table->entries;

we are seeing a warning stating "Use of uninitialised value of size 4"

I'm thinking it's the entries array element 0 not being initialized in
the PropertyMapHashTable

struct PropertyMapHashTable
   int sizeMask;
   int size;
   int keyCount;
   int sentinelCount;
   int lastIndexUsed;
   PropertyMapHashTableEntry entries[1];

Though not 100% sure.
