[389-users] Re: replication problems

William,

Here's:

(gdb) frame 3
#3  0x00007ffff7b71627 in slapi_valueset_done (vs=0x7fff8c022aa8) at ldap/servers/slapd/valueset.c:471
471        PR_ASSERT((vs->sorted == NULL) || (vs->num < VALUESET_ARRAY_SORT_THRESHOLD) || ((vs->num >= VALUESET_ARRAY_SORT_THRESHOLD) && (vs->sorted[0] < vs->num)));
(gdb) print *vs
$1 = {num = 21, max = 32, sorted = 0x7fff8c023ad0, va = 0x7fff8c022b50}

Thanks,

Alberto Viana

So that assert seems to be:

PR_ASSERT((vs->sorted == NULL) || (vs->num < VALUESET_ARRAY_SORT_THRESHOLD) || ((vs->num >= VALUESET_ARRAY_SORT_THRESHOLD) && (vs->sorted[0] < vs->num)));

But it's not clear which condition here is being violated.

It looks like your catching this in GDB though, so can you go to:

https://gist.github.com/albertocrj/4d74732e4e357fbc5a27296199127a62

(gdb) frame 3
(gdb) print *vs

That would help to work out what condition is incorrectly being asserted here.

Thanks!
