Problem description: When client loses the connection to the MySQL server or if the server gets shutdown after mysql_stmt_prepare() then the next mysql_stmt_prepare() will return an error(as expected) but consecutive call mysql_stmt_execute(), will crash the client program. The expected behavior would be, it should through an error. Analysis: The mysql_stmt_prepare() interns calls the function end_server() and net->vio and net->buff are freed and set to NULL. Then the next call mysql_stmt_execute() will interns call net_clear() where we are "net->vio" with out validating it. Fix: we are validating the net->vio, before calling net_clear(). |
