20 iOS api tests are crashing after system update These tests are crashing all with "Child process terminated with signal 11: Segmentation fault" Stdio: https://build.webkit.org/builders/Apple%20iOS%2013%20Simulator%20Release%20WK2%20%28Tests%29/builds/2341/steps/run-api-tests/logs/stdio These are very flaky crashes and we are seeing 7-12 crashes fairly consistently. The only one I am able to reproduce reliably with iterations is: TestWebKitAPI.KeyboardInputTests.SupportsImagePaste

Looking at the code, my guess is that we someone have a test somehow not associated with a file or a line number. If we have a reliable reproduction, I can probably fix it. Building now to test.

I can fix the crash, but the crash is just surprising another error, likely an uncaught C++ exception (for TestWebKitAPI.KeyboardInputTests.SupportsImagePaste), but I haven't run all of the effected tests.
