Description:
When call directly to sp "proc" not have problem with the cursors.

When call to sp "proc" from the function "func" for some reason are verifying if the tables ("d" and "l") of the cursors ("g" and "h") exist, generating an error.

How to repeat:
Procedure:

DELIMITER $$

DROP PROCEDURE IF EXISTS `proc`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `proc`()
BEGIN
	declare h cursor for select value from l;
	declare g cursor for select value from d;
	select '1' as Valor;
    END$$

DELIMITER ;

Function:

DELIMITER $$

DROP FUNCTION IF EXISTS `func`$$

CREATE DEFINER=`root`@`localhost` FUNCTION `func`() RETURNS int(11)
BEGIN
	call proc();
	return 1;
    END$$

DELIMITER ;

Test 1:

/* WORK */
call proc();

Result:

Valor 
------
1 

Test 2:

/* NOT WORK */
SELECT func();

Result:

Error Code : 1146
Table '[schema].d' doesn't exist
