I think this issue has been already fixed, incidentally, in HEAD/re24, but
went unnoticed in re23.  You should replace the call to ch_malloc() that's
around line 1140 in servers/slapd/overlays/pcache.c with a call to
ch_calloc(); something like

        *new_attrs = (AttributeName*)ch_calloc( count + 1,
                sizeof(AttributeName));

(sorry, I can't access the network right now but by webmail).  In fact,
right now, the array of AttributeName "new_attrs" is accessed by an_find()
while not yet NULL terminated.  Please check and report (to create the
problem, you need to use filters that contain the attributes that will be
cached).
