This bug could manifest itself when hash join over a varchar column with NULL values in some rows was used. It happened because the function key_buf_cmp erroneously returned FALSE when one of the joined key fields was null while the second was not. Also fixed two other bugs in the functions key_hashnr and key_buf_cmp that could possibly lead to wrong results for some queries that used hash join over several columns with nulls. Also reverted the latest addition of the test case for bug #45092. It had been already backported earlier. It looks good to be pushed. Thank you for fixing it!
