WebKitTestRunner allocates a main PlatformWebView on the heap and never destroys it. It should clean up after itself!
See also bug 42828, which is triggered by this bug.
It's possible that this is a cause of bug 42785. See discussion in that bug for more details.

I added some code to the end of TestController::run that deletes m_mainWebView. This causes a crash in the web process on Mac. It crashes in CoreIPC::Connection::dispatchConnectionDidClose because m_client is null. dispatchConnectionDidClose must be getting called twice.

It crashes in CoreIPC::Connection::dispatchConnectionDidClose because m_client is null. dispatchConnectionDidClose must be getting called twice. Anders fixed this crash in r63916.
This was fixed in r64485.
