           Summary: Regular expressions with ".?" expressions at the start
                    and the end match the entire string
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: till at tillschneidereit.net


STR:

Execute the following code in JSC:

'abcdefghijk'.match('.?e.?')

Expected result:
def

Actual result:
abcdefghijk


This also happens in SpiderMonkey, so it's almost guaranteed to be a Yarr issue.
