MySQL Procedure compile completes w/o error but also w/o ANY notification

I even have SQL_MODE = 'STRICT_TRANS_TABLES' set, hoping I'd find some cause.

I can't find any reference to this in my search so far.

DROP PROCEDURE ImportCellModemPlans_ATnT ;

SET @OLD_SQL_MODE = @@SQL_MODE , SQL_MODE = 'STRICT_TRANS_TABLES' ;
DELIMITER &&

CREATE PROCEDURE `ImportCellModemPlans_ATnT`(IN param_invoice_id INTEGER, IN param_invoice_identifier VARCHAR(50), IN take_notice TINYINT )
BEGIN
... 1300 lines later...
END &&

DELIMITER ;
SET SQL_MODE = @OLD_SQL_MODE ;

Any suggestions on what to look for?

I'm using MySQL Workbench 6.3 on Windows 7.  Seems a bit more buggy than the 6.2 version I used to use.

Thanks!
