Actually, this is arm64 specific.

[Alex Christensen]

Strange.  This has something to do with this line:

return HTTPResponse({ { "Set-Cookie"_s, "testCookie=42; Path=/; SameSite=None; Secure"_s } }, "<script>alert('hi')</script>"_s);

If I write it out by making a HashMap<String, String>, add to it, then move it to the HTTPResponse constructor it works fine.  So this isn't a big deal.  I'd like to understand a bit more about this then fix it.

Should the comment say arm64 now?

I think this is an arm64e bug, but to be conservative I'm enabling the workaround on all arm64 CPUs.
