           Summary: JSC: Change stack recursion checks to be based on
                    stack availability
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mark.lam at apple.com


Some existing stack checks are based on  max reentry depth estimates.  Fix these checks to be based on actual available stack space.  Also fix the JSStack to reserve some space for error handling so that we won't end up throwing a StackOverflowError when processing (throwing and reporting) an exception.
