We are using 2.3.37 for both master and slave, and have confirmed that disactivating the rwm overlay in slapd.conf avoids the problem.

The failure is related to the fact that you rewrite the bindDN; this tricks slapo-rwm(5) into failing to recognize that the operation is actually an update, resulting in a double free at cleanup. I'll check if this could also happen with syncrepl, and try to figure out a workaround. In the meanwhile you should be able to solve the problem by reworking the bindDN rewrite rules so that the updatedn is not rewritten.
