           Summary: Linux crashes during boot
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: http://www.ubercomp.com/jslm32/src/
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


The bug here is that we add empty JSValues to the sparse map, and then set them - but a GC may occur before doing so (due to a call to reportExtraMemory cost).
We may want to consider making it safe to mark empty JSValues, but the simple & contained fix to this specific bug is to just initialize these values to something other than JSValue().
