Bug 43156 - Memory corruption when processing time stamped digital alarms.

While using timestamped digital alarms, users may find that the CitectSCADA
runtime may crash during shut down. This problem has now been resolved.

Bug 44090 - CitectSCADA Crashing on Shutdown and alarm summary information
missing when using time stamped digital alarms with tag values in the description.

A shutdown crash may occur when exiting citect while repeatedly triggering time
stamped digital alarms with tag values in the description. In additon the same
alarms may not generate expected alarm summary events. These problems have now
been resolved.

Bug 44853 - DisplayDisable=1 from Bug 31976 produces unexpected results.

When using [Alarm]DisplayDisable=1 the following unexpected behaviour can be
observed.

All other alarms besides the "Time Stamped Digital" and "Time Stamped Analog"
alarms cause an extra alarm summary event if an alarm is disabled and then
re-enabled.

Disabling and triggering a "Time Stamped", "Time Stamped Digital" or "Time
Stamped Analog" alarm causes the alarms to "disappear"; meaning that the alarm
neither exists on the alarm page or the disabled alarm page. A further
untriggering of the alarms then makes the "Time Stamped" alarm reappear. This
has now been resolved.
