Looking to see if I can find any other information.  Failure to attach a crash-log usually means that a crash has (In reply to Ryan Haddad from comment #4)

It's possible that this is a test harness failure.

Here is the stdout of that test run: https://build.webkit.org/builders/Apple%20Sierra%20Release%20WK2%20%28Tests%29/builds/2469/steps/layout-test/logs/stdio.

Looking at the logging, we are actually killing the test runner because it doesn't have output when we expect it to.

Saam, is this test expected to take a long time?  Are their possible race conditions?  Or do we expect there to be a lot of output on this test?  I'd bet that this is something time-outy, we're hitting the code-path where we attempt to read from the test runner's stdout but fail.
