           Summary: svg/custom/mask-excesive-malloc.svg crashes on feature
                    branch
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh PowerPC
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P1
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ap at webkit.org


Crashes both a local debug build (Safari or DRT) and r26041 nightly. Works fine
in r25809 trunk nightly.

I'm testing on a G4; Rob says this doesn't happen on an MBP.
