The following code crashes (segmentation fault) every time :
<?php
$var = 'crash__'.getmypid().'_'.time();
$options = array('persist_to' => 1, 'replicate_to' => 0);
$cluster = new CouchbaseCluster('couchbase://10.0.0.100','test','');
$bucket = $cluster->openBucket('test');
$resp = $bucket->insert($var, 123456, $options);
$bucket->remove($var,$options); // remove crashes if persist_to is set !
If persist_to is not set in $options then remove works as expected.
I can provide a core dump / stack trace if necessary.
The couchbase cluster i used for testing has only 1 node.
The server is Couchbase CE 3.0.1.
