percorna toolkit 2.2.13 - ​pt-online-schema-change bus error (core dumped)

cirpocirpo EntrantInactive User Role Beginner
Hi,

I'm using pt-online-schema-change for altering a table on mysql 5.6 on ubuntu 14.10, but with no success.

After "2015-03-12T15:08:06 Dropped new table OK." I get "bus error (core dumped)".

This is the command I'm running:
pt-online-schema-change --version-check --user root --password xxxx --database test h=127.0.0.1,t=order_item --alter-foreign-keys-method "rebuild_constraints" --alter "ADD COLUMN refunded_by varchar(255) DEFAULT NULL" --execute

and this is the output:
➜ pt-online-schema-change --version-check --user root --password xxxx --database test h=127.0.0.1,t=order_item --alter-foreign-keys-method "rebuild_constraints" --alter "ADD COLUMN refund_by varchar(255) DEFAULT NULL" --execute
No slaves found. See --recursion-method if host cirpux has slaves.
Not checking slave lag because no slaves were found and --check-slave-lag was not specified.
Operation, tries, wait:
copy_rows, 10, 0.25
create_triggers, 10, 1
drop_triggers, 10, 1

Child tables:
`test`.`sales_order_item_status_history` (approx. 1 rows)
`test`.`sales_return` (approx. 1 rows)
Will use the rebuild_constraints method to update foreign keys.

Do you have any suggestions on how to get more information on what's going on? Or even a solution :P


thanks
