Regexps doesn't work correctly in the current nightly build. The attached page url will test a complex regexp it's currently failing in WebKit nightly but works on older versions before WebKit-r72493 so this was the point it was introduced it also works on other browsers so this is a clear regression. Steps to reproduce: 1. Open the attached URL in latest WebKit nightly. 2. Press the test link. 3. Observe the alert message about the regexp match failing. 4. Compare to older versions before WebKit-r72493 and other browsers all are passing. It seems to have something to do with back references in Regexps but I didn't dig to deep in it.
Is this the same as bug 54978 (fixed today)?
