Though, it might not be able to reproduce the issue locally, tried it to make sure.

First, I tried to reproduce it by running all tests with multiple workers (run-webkit-tests --force --exit-after-n-crashes-or-timeouts 1000 --exit-after-n-failures 1000 --no-build --no-show-results --no-new-test-results --clobber-old-results --ios-simulator --debug --child-processes 8), but got (most likely) unrelated error, "OSError: [Errno 9] Bad file descriptor (from worker/6)", and it stopped running tests.

Next, tried with test lists (See attached list) with a single worker. Got the same error (OSError: [Errno 9] Bad file descriptor).

Next, tried with test lists with multiple workers. Tests ran successfully, but the test in question (fast/viewport/scroll-delegates-switch-on-page-with-no-composition-mode-asserts.html) didn't "crash".
