Description Karl Rackler 2023-09-15 13:04:47 PDT

Description:
imported/w3c/web-platform-tests/preload/link-header-preload-non-html.html

Is a flaky crash on macOS ToT and since 260462@main when the test was added.  The test was added as part of web-platform-tests/preload resync and 260462@main is not the cause of the Assertion, but just when the test was added and uncovered a pre-existing condition.

This issue can be bisected to 260462@main using the command: 
run-webkit-tests --debug -f --clobber-old-results --exit-after-n-failures 1  --force  --child-processes=5 --iterations=50 -1  imported/w3c/web-platform-tests/preload/link-header-preload-non-html.html
