Without digging deeper, it seems to me that there is an outer deadline from
another WITH-DEADLINE. In the old version you're using :OVERRIDE, which means
that even if you specify a longer wait, you get what you ask for.
In the new version the outer WITH-DEADLINE specifies a shorter wait
than the :TIMEOUT you request, and that happens -- and a
deadline-timeout is signalled, etc.
Using bleeding edge SBCL and
'(sb-sys:with-deadline (:seconds nil :override t)
(sb-thread:condition-wait waitqueue mutex
in the first leg, the tests pass after removing
nil ; FIXME: :timeout doesn't work. Why?
...but since ability to specify :SECONDS NIL is very new, it's
probably best not to depend on that just now. Finding the outer source
of deadline is probably a better bet.
