Collisions on small consecutive numbers mean hash-tables will be slower than expected, and systematic such collisions probably count as a performance bug.

(EQUAL (SXHASH 12) (SXHASH 13))

gz says it looks like 2n and 2n+1 can have same SXHASH, and gb points at CCL::STRIP-TAG-TO-FIXNUM.

Remarkably, the CLHS entry for PROBE-FILE doesn't seem to mention *DEFAULT-PATHNAME-DEFAULTS* or MERGE-PATHNAMES, unlike OPEN which at least mentions the latter and implies its use. So that makes PROBE-FILE also subtly different from OPEN (assuming OPEN is unaffected -- is it? I have tested). ​http://clhs.lisp.se/Body/f_probe_.htm

In any case, this is probably a bug, and if not, a change that should be prominently documented.
