in ThreadManager::StopAll() there is item.thread_item_data pointer which was freed (the pointer was pointing to an object with a log_buffer)
but internal Log buffer from item.object was pointing to that object and when thread_tab.clear() was called then the d-ctor was called
and then save_log_and_clear() method was called and tried to use the freed object.

Tomasz Sowa b90445de4a updated to the new pikotools api - we have a logger for morm and ezc
pikotools has now Log and FileLog classes
which are base classes for winix Log and FileLog classes

Tomasz Sowa 491dd27ebf some work in the new api:
- log_level and save_each_line moved from Log to FileLog
- other fixes in loggers
- DirContainer from Dirs and LoadAvg had no dependencies set

Tomasz Sowa a2ffc1e81c start working on 0.7.x branch
- added FileLog which stores content to the file log
- now Log is only a wrapper - it puts messages to the local buffer and when logsave is used then the buffer is put to FileLog
- new base classes:
  WinixBase (Log, Config*, Synchro*)
  WinixModel : public WinixBase (morm::ModelConnector*, Plugin*)
  WinixSystem : public WinixModel (System*)
  WinixRequest : public WinixSystem (SLog, Cur*)
- singletons: log, slog, plugin are depracated - now references to them are in base classses (WinixBase, WinixModel)
- DbBase,  DbConn and Db are depracated - now we are using Morm project (in WinixModel there is a model_connector pointer)
  each thread will have its own ModelConnector
