Bug description: WHERE column > -1 crashes but WHERE column < -1 or WHERE
column = 1 are fine
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.
