>Description:
	Hello,
	I got
	ERROR 2013: Lost connection to MySQL server during query.
>How-To-Repeat:
	
	I had uploaded file 'select_distinct-ssk.tar.gz' with simple test
	case to ftp://support.mysql.com/pub/mysql/secret.

	Query: 
	select distinct s.supplier_id, s.who_pay, r.name as rname, s.name,
                    s.nick, s.address, s.contact_person, s.email, s.fax,
                    s.comment
	from supplier s, product_supplier ps, shop_product_supplier sps
	use index(product_supplier_id)
	left join route r on r.route_id=s.route_id
	where ps.product_supplier_id=sps.product_supplier_id and
	sps.shop_id=10 and ps.supplier_id=s.supplier_id
	order by name
	limit 0, 10

	Result:
		ERROR 2013: Lost connection to MySQL server during query
	
	Note: MySQL was compiled with both gcc-3.1 and gcc-2.95.3,
	this doesn't matter, the result is the same.
	
>Fix:
	don't use distinct
