MySQL/MariaDB parsing problem

I have a stored procedure created in an .sql file:

DROP PROCEDURE IF EXISTS sp_groups_saveGroup;

DELIMITER //

CREATE DEFINER = INVOKER

  PROCEDURE sp_groups_saveGroup(
          IN in_groupId INT UNSIGNED,
          IN in_groupCode VARCHAR(32),
          IN in_groupTitle VARCHAR(128),
          IN in_description VARCHAR(255),

When I redirect it into MySql (MariaDB) on the command line, it works fine.

When I 'Execute' it within PHPStorm (PS-143-279) I get:

[2015-10-23 12:21:57] Run /Users/david/TasoMedia/utah/build/mysql/sprocs/groups/groups_saveGroup.sql

CREATE DEFINER = INVOKER

  PROCEDURE sp_groups_saveGroup(
          IN in_groupId INT UNSIGNED,
...

Is this an EAP issue? Something to do with switching to MariaDB from Mysql? Can't fathom it myself.
