Problem: ======== CHANGE MASTER TO MASTER_USER='root', MASTER_SSL=0, MASTER_SSL_CA='', MASTER_SSL_CERT='', MASTER_SSL_KEY='', MASTER_SSL_CRL='', MASTER_SSL_CRLPATH=''; CHANGE MASTER TO MASTER_USER='root', MASTER_PASSWORD='', MASTER_SSL=0; use-after-poison is reported for lex_mi->ssl_crl File: sql_repl.cc if (lex_mi->ssl_crl) strmake_buf(mi->ssl_crl, lex_mi->ssl_crl); Analysis: ======== At the end of CHANGE MASTER statement execution, the LEX_MASTER_INFO parameters are reset so that the next query will have a clean state. But 'ssl_crl' and 'ssl_crl_path' members of LEX_MASTER_INFO object are not cleared during 'LEX_MASTER_INFO::reset'. Hence when a new CHANGE MASTER statement is executed, the stale value of lex_mi->ssl_crl is used, so ASAN reports use-after-poison. Fix: === Clear 'ssl_crl' and 'ssl_crl_path' as part of 'reset'.
