Comment(by ryan):

 {{{
 WP_Query('posts_per_page=15&cat=-21072,-37613,-4533907');
 }}}

 Generates a query like:

 {{{
 SELECT SQL_CALC_FOUND_ROWS  wp_3508545_posts.* FROM wp_3508545_posts
 WHERE 1=1  AND wp_3508545_posts.ID IN(0, 14, 17, 25
 }}}

 Where the post ID list has 1666871 IDs and the resulting query is 1.2
 million characters long. This causes segfaults.
