 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
