           Summary: RegExp.prototype.toString does not escape slashes
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jandemooij at gmail.com


Consider this: RegExp("abc/def").toString()

Result in FF and Opera: /abc\/def/
Result in Chrome and Safari: /abc/def/

It does work correctly for literal regexps like /abc\/def/.toString()

ES5 15.10.6.4 mentions this:
===
NOTE The returned String has the form of a RegularExpressionLiteral that evaluates to another RegExp object with the same behaviour as this object.
===
/abc/def/ is invalid as regexp literal, so the behavior is different in Safari/Chrome.

FWIW, here is the V8 bug: http://code.google.com/p/v8/issues/detail?id=956
