Description:
------------
The query below causes mysql_query() to crash without 
php without error. The original query:

SELECT b189_start, b189_end, product_level1.Id AS id, 
product_level1.a001 AS a001, b014 AS description, 
FORMAT(price.j151, 2) AS price, images.Name AS 
product_image, CONCAT_WS(': ', b028, b029) AS title
FROM product_level1 
LEFT JOIN product_webcategory_x ON 
(product_level1.ID=product_webcategory_x.ID_product) 
LEFT JOIN codes ON 
(product_webcategory_x.ID_category=codes.ID) 
LEFT JOIN price ON (product_level1.a001=price.a001) 
LEFT JOIN images ON (product_level1.a001 = 
images.ProductID) 
WHERE ( b189_start >= -1 AND b189_start <= 3) AND 
(b189_end <= 3 ) AND ( price.j151 > 0 ) AND (price.j151 
IS NOT NULL) AND ( xWebInactive < 1 ) 
GROUP BY product_level1.ID 
ORDER BY b028, b029

I have tracked the probelm down to the WHERE condition 
with ">" and negative numbers. For example, if I change

"b189_start >= -1" to "b189_start = -1" or "b189_start < 
-1" The problem crash does not occur.
