            Bug ID: 212543
           Summary: Do not install the VMTraps signal handler if
                    Options::useJIT=false.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

VMTraps is only needed for JITted code.  Hence, if the JIT is disabled, we should set Options::usePollingTraps() to true to indicate that we won't be using VMTraps.
