Before sorting HAVING condition is split into two parts, first part is a table related condition and the rest of is HAVING part. Extraction of HAVING part does not take into account the fact that some of conditions might be non-const but have 'used_tables' == 0 (independent subqueries) and because of that these conditions are cut off by make_cond_for_table() function. The fix is to use (table_map) 0 instead of used_tables in third argument for make_cond_for_table() function. It allows to extract elements which belong to sorted table and in addition elements which are independend subqueries.
