TYPO3 Core

The sys_page->getRootline function just stops if pid 0 is found.

The root of a tree is not always the page 0.

e.g.

typo3(0)
-rootpage
--domain1
--domain2

this causes the behaviour that typolink between domains even with the flag config.typolinkLinkAccessRestrictedPages do not work.

Solution:

the rootline parsing should end in this case if the flag "is_siteroot" is set.
