Running 'truncate table' command at a cluster node, when binlog files are not used, will cause a segfault:
Howto reproduce:
1. Start a cluster with no log_bin option set.
2. create just any table, .e.g.: create table a (i int) engine=innodb;
3. issue: truncate table a:
The first node will crash with following stack trace:
{{{
Program received signal SIGSEGV, Segmentation fault.
