I am unable to reproduce the issue with r256090 with the following command:
run-webkit-tests http/wpt/cache-storage/cache-put-keys.https.any.html --force --exit-after-n-failures 5 --iterations 5000 --force

Also, I have marked the test as Skip while this is investigated.
Changeset in webkit [256210].

This is the same test as bug 177691, bug the posted failure diff is different.

Comment 5 Jacob Uphoff 2020-04-07 16:14:19 PDT

I unskilled the test in expectations and set it to [ Pass Fail ] so hopefully we will get some better idea of this test's behavior in the next few days.
