            Bug ID: 188895
           Summary: YARR: Need to JIT compile a RegExp before using
                    containsNestedSubpatterns flag
           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: msaboff at apple.com

There is a slight bug in the RegExp JIT code where we use the m_containsNestedSubpatterns before the JIT compilation has set it.  The result is that this limits somewhat the regexps that can take advantage of JIT'ed greedy sub patterns.
