Description Karl Rackler 2022-05-03 10:40:12 PDT

This test is constant failing one [ iOS Release ] and constant crashing on [ iOS Debug ].  The first failure that I saw on the dashboard was 4/26/2022 r293432, but does not seem relevant. 

Commit r293427 at Canonical link: https://commits.webkit.org/249987@main | git-svn-id: https://svn.webkit.org/repository/webkit/trunk@293427 268f45cc-cd09-0410-ab3c-d52691b4dbfc modified some files that seem to have introduced the constant failures and crashes. 

I can reproduce this constant failure and constant crash on r293427, but am unable to reproduce it on r293426 or earlier.

View in context: https://bugs.webkit.org/attachment.cgi?id=458761&action=review

Looks reasonable to me!

(It would be nice if Alex, Brady, and/or Chris could take a look too)

Nit - mark this const?

> Source/WebCore/loader/DocumentLoader.h:507
> +    bool isLoadingRemoteArchive();

(const here too)
