116568 2013-05-21 12:31:45 -0700 [WK2] WebKitTestRunner always crashes on exit 2013-05-21 13:37:59 -0700 1 1 1 Unclassified WebKit Tools / Tests 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED InRadar P2 Normal --- 1 ap ap andersca jonlee sam oldest_to_newest 891945 0 ap 2013-05-21 12:31:45 -0700 I'm always getting a crash in WebContextSupplement::deref when WebKitTestRunner exits. What happens here is that WebKitTestRunner destroys WTR::WebNotificationProvider when done, but WebKit doesn't know that. So when WebContext is destroyed, it calls into the deleted provider object. void WebNotificationManagerProxy::contextDestroyed() { m_provider.removeNotificationManager(this); }
