    Description

      https://bugs.launchpad.net/maria/+bug/959701

      When a client problem is executed with --version, or --help, or without parameters, it throws warnings about lost bytes, e.g.

      Warning: 484 bytes lost, allocated at mysys/my_alloc.c:217, mysys/default.c:1203, mysys/default.c:524, mysys/default.c:468, client/mysqladmin.cc:310, ??:0
      		 
      Warning: 1024 bytes lost, allocated at mysys/array.c:65, mysys/hash.c:92, mysys/thr_mutex.c:186, mysys/thr_mutex.c:323, sql-common/client_plugin.c:262, libmysql/libmysql.c:134, sql-common/client.c:1708, client/mysqladmin.cc:310
      		 
      Warning: 1024 bytes lost, allocated at mysys/array.c:65, mysys/hash.c:92, mysys/thr_mutex.c:181, mysys/thr_mutex.c:323, sql-common/client_plugin.c:262, libmysql/libmysql.c:134, sql-common/client.c:1708, client/mysqladmin.cc:310

      etc.

      From the standard set of binaries produced with DCMAKE_BUILD_TYPE=Debug without any other parameters, observed on

      • mysqladmin
      • mysqlcheck
      • mysqldump (it's message also looks strange: (Warning: 15 bytes lost, allocated at addr2line: 'mysqldump': No such file")
      • mysqlimport
      • mysql_plugin
      • mysqlshow
      • mysqlslap
      • mysql_upgrade

      revno: 3329

      Not reproducible on maria/5.3, mysql-server/5.5, mysql-server/trunk.

      To reproduce,

      • build the client program using cmake .. -DCMAKE_BUILD_TYPE=Debug && make;
      • start the client program, e.g. client/mysqladmin --help
      • see output.
