HI!
I'm experiencing occasional seg faults with 2.4.22 while 2.4.21 worked without issues on the very same system (self-compiled BDB, SASL, OpenLDAP on RHEL 5 with separate prefix) with the very same configuration. I can't provide a stack trace since data on this system is private.
I suspect that something's wrong with slapo-allowed and deactivated it. Have to observe that a little bit more since the problems seem to be not deterministic. Were some API changes done in 2.4.22 which are not propagated to slapo-allowed?
slapo-allowed was modified between 2.4.21 and 2.4.22; support for allowedChildClasses and allowedChildClassesEffective was added.
Looking at the diff, I don't see room for any (known) API/semantics change. Could you please backtrace the stack of next core dump?
p.
