This means that signal handlers in applications making use

One exception to this rule is for signals raised in response

(3) Special care should be taken when using tagged pointers,

virtual addresses differing only in the upper byte.
The architecture prevents the use of a tagged PC, so the upper byte will
be set to a sign-extension of bit 55 on exception return.
