    Description

      The following procedure, using the RAND() function, crashes the server when called more than once.

      DELIMITER $$
      		 
       
      		 
      DROP PROCEDURE IF EXISTS sp_test;
      		 
      $$
      		 
      CREATE PROCEDURE sp_test(
      		 
      )
      		 
      BEGIN
      		 
       
      		 
      	SELECT x, y
      		 
      	FROM (
      		 
      		SELECT x, RAND() y
      		 
      		FROM (
      		 
      			SELECT 1 x
      		 
      			UNION
      		 
      			SELECT 2
      		 
      		) SQ0
      		 
      	) SQ1;
