Hi Pierangelo; Sorry for the stripped code. Below you find a backtrace of slapd 2.4.4alpha with the non-stripped code :
(gdb) bt #0 0x00889d5a in strcmp () from /lib/tls/libc.so.6 #1 0x08068ede in select_backend (dn=0xa2f4df5c, manageDSAit=0, noSubs=0) at backend.c:684 #2 0x0806a8ac in fe_aux_operational (op=0xa2f4df40, rs=0xa2f4de80) at backend.c:1779 #3 0x0806a01b in backend_operational (op=0xa2f4df40, rs=0xa2f4de80) at backend.c:1801 #4 0x080a7d06 in do_syncrepl (ctx=0xa2f4e2a0, arg=0x8695fb0) at syncrepl.c:547 #5 0x081281cb in ldap_int_thread_pool_wrapper (xpool=0x865ad78) at tpool.c:704 #6 0x00bb6371 in start_thread () from /lib/tls/libpthread.so.0 #7 0x008e8ffe in clone () from /lib/tls/libc.so.6 (gdb)
Likely because you used a stripped binary. Can you reproduce the issue with a non-stripped build of HEAD?
p.
