In "while" loop at 2656, I find old->a_vals are like [..., a, b, ...] and new->a_vals are like [..., b, a, ...].

Matches are found at old [i] == new [k = j+1] and old [k = i+1] == new [j], but this just shows that neither an add nor a delete is called for, and the loop end is reached without having incremented i or j.

Actual attribute values I'm looking at right now in the debugger are eduPersonAffiliation: old [ member, alum, employee, faculty ], new [ member, alum, faculty, employee ]. I built the replica from a slapcat dump on the idle master, started the slapd syncrepl client and applied a lot of normal modifications to the master, until it hit the infinite loop. It has been a recurrent problem.

Now fixed in HEAD, please test.
