Seg fault if delete tuple through loop

[baltazorbest]

Hello.
I have Tarantool 1.7.1-123-g17673d5 and php 7.0.9
If I try delete tuple through loop, I have segmentation fault.
PHP script example:
<?php $tnt = new Tarantool('remote_ip:3301'); $tnt->connect(); $space = "test"; $key = "test2"; for($i=0;$i<=1000;$i++) { $tnt->delete($space, $key . $i); }

If I try delete tuple through loop with $i=1000 and $i<=100000 - All ok.
