           Summary: Strange relation between script loading and call stack
                    size
           Product: WebKit
           Version: 525.x (Safari 3.1)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P3
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fabian.jakobs at 1und1.de


I have a very strange problem with Safari 3.1.2 and WebKit nightly. We
use a loader script, which inserts script tags dynamically into the
header. Now I observe the strange behavior that doing so seems to limit
the available call stack size. We load many scripts (> 300) in a loop
this way and run into an call stack size exceeded error.

I have reduced the problem to the attached HTML, where you can see the
effect. Still I have problems interpreting the results. Safari 3.1.2
shows me a decrease of the available call stack size, while it does not
really work in the Nightly. What is happening inside of Safari there?
