           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: NeedsRadar, Regression
          Severity: Normal
          Priority: P2
         Component: CSS

To see the leaks:

1. Go to <http://build.webkit.org/LeaksViewer/?url=http://build.webkit.org/results/SnowLeopard%20Intel%20Leaks/r82400%20(15899)/>
2. Dig into malloc_zone_malloc > malloc -> WTF::fastMalloc

The first leak listed here is an allocation inside Vector. If you look a little lower down you'll see the Vector itself is leaking (as indicated by the Vector<OwnPtr<CSSParserSelector> >::operator new leak).
