            Bug ID: 184074
           Summary: A stack overflow in the parsing of a builtin (called
                    by createExecutable) cause a crash instead of a
                    catchable js exception
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: rmorisset at apple.com

Fixing this will require quite a lot of plumbing, since throwing an exception needs both the ParserError and an ExecState, and there is a dozen levels to the call stack between the last place to get an ExecState and createExecutable (that currently crashes upon encountering a ParserError).
