           Summary: On Apple Windows port, running DRT locally crashes
                    after r128583 and related changes
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows 7
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: roger_fong at apple.com
                CC: tkent at chromium.org


The crash resolves in hash table code. 
When DRT calls WebKitCreateInstance it tries to populate a hash table. At some point it needs to expand the table and reinsert objects into the new larger table but for some reason one of the objects it tries to reinsert has been marked as deleted and things go downhill from there.

This problem only reproduces locally on my Windows machine. The Apple Windows port test bots don't seem to have the same issue.

Originally, there were crashes occuring after r128583. These were fixed later by a workaround and then an actual fix in r128850.

I failed to notice this fix while I was bisecting but I believe that the crashing form r128583 and the ones occuring now are because of different reasons. Most likely soething after r 128850 made things crash again.

I'm going to investigate r128850 to see whether or not the crashes still occur at that revision.
