That's not a bug.  It should work to do `sudo -s $SHELL` if you want
to keep using the same shell version.

This isn't entirely surprising ... those signals might fail because
your user doesn't have privilege to signal the root shell.

Does there happen to be a Time Machine backup under
/System/Volumes/Data/ ?  Time Machine plays some tricks with making
hard links to directories (normally not allowed) for reasons of space
savings, but that could put **/ into an infinite loop.
