This has started to happen after r218165, but I don't think it's a regression, but that r218165 revealed the bug somehow in WTR. The problem is that GeolocationProviderMock keeps a pointer to the WKGeolocationManagerRef returned by WKContextGetGeolocationManager. But in TestController::generatePageConfiguration() the context is freed before the GeolocationProviderMock. When the GeolocationProviderMock is then destroyed, it calls WKGeolocationManagerSetProvider(m_geolocationManager, 0); but the WKGeolocationManagerRef has already been destroyed.
