Fixed <rdar://problem/5065399> REGRESSION: leaks in Frame::bindingRootObject seen on buildbot The problem was that we were initializing the same WebScriptObject twice. This caused it to leak its original set of ivars. I think some refactoring could prevent this situation from arising in the first place, but I'm just adding a check at the call site for now, to do the simplest thing. * bindings/objc/WebScriptObject.mm: (-[WebScriptObject _setImp:originRootObject:rootObject:]): Added ASSERTs against multiple calls. * bindings/objc/WebScriptObjectPrivate.h: Renamed _initializeWithObjectImp to setImp because "init" vs "initialize" was a too subtle indication that one was a Cocoa initializer and one was not. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@20240 268f45cc-cd09-0410-ab3c-d52691b4dbfc
