Mojave WK1 Crash
The following layout test is flaky on Mojave WK1 and iOS Simulator Release WK2
Test has been crashing for some time, most recent fix was https://trac.webkit.org/changeset/242723/webkit
I can reproduce locally on Mojave WK1 with 5000 iterations I got it to crash once. (will attach crash logs).
I can reproduce the iOS Sim much easier, it crashed 9 times in 18 iterations before I stopped it (will attach crash logs).

iOS Sim Crash
Updated test expectations in https://trac.webkit.org/changeset/243521/webkit
Was marked Pass Fail before, added Crash to the expectation file.
I'll continue to try to reproduce this and look into how to fix it.
I just finished running this test 20000 times with 0 crashes. Here is what I used to run it:
run-webkit-tests --release --iterations=100 --repeat-each=200 -1 imported/w3c/web-platform-tests/xhr/send-redirect-post-upload.htm

Sometimes, adding -gf helps:
run-webkit-tests --release --repeat-each=200 -1 -gf imported/w3c/web-platform-tests/xhr/send-redirect-post-upload.htm
I have used -gf as well in the past as well.
In this particular case I did:
run-webkit-tests imported/w3c/web-platform-tests/xhr/send-redirect-post-upload.htm --iterations 5000 -1 -f
To state the obvious, Mac and iOS crash signatures look quite different.

bug 159724 makes the two crashes the same. Since no increased crash rate was observed in Mojave WK2, it will not affect Safari updates.
