Study the impact of integrating v22 exceptions and postmortem traces.

[sowebio]

In addition to the usual trace, a v22 exception give some extra information like: exception time, program uptime, program & library names & versions, start & home directories and Ada and all languages memory allocation, current & maximum (peak) values. In addition, v22 closes open DB connections after the trace has been output.

I'm obviously open to extend this code to Mac OS with atos command...

User logging feature allows to customize exception logger, see changes for align.adb and add:

   overriding procedure Log
     (Object     :    User_Defined_Logging_Type;
      Message    : in String;
      Occurrence : in Ada.Exceptions.Exception_Occurrence);

with your own code inside Log body.
