This is reproducible for me by running a single test: $ run-api-tests TestWebKitAPI.WKWebViewTitlebarSeparatorTests.BackForwardCache Running tests LEAK: 1 WebProcessPool LEAK: 1 WebPageProxy File name unavailable Unknown C++ exception thrown in the test body. TestWebKitAPI.WKWebViewTitlebarSeparatorTests.BackForwardCache Failed Ran 1 tests of 1 with 0 successful ------------------------------ Test suite failed Failed TestWebKitAPI.WKWebViewTitlebarSeparatorTests.BackForwardCache LEAK: 1 WebProcessPool LEAK: 1 WebPageProxy File name unavailable Unknown C++ exception thrown in the test body.
