There were two issues: * set_var_default_role::user was overwritten with a new value, allocated in the thd->mem_root, which is reset between executions. That was causing the crash. Solved by introducing set_var_default_role::real_user * when privilege tables were opened on EXECUTE, the reprepare_observer would abort the statement (as privilege tables are opened using the local TABLE_LIST that doesn't preserve metadata from PREPARE, so reprepare_observer thought they're changed). This issue also applied to SET PASSWORD. Solved by disabling reprepare_observer.
