OPC UA communication stops (corrected from V3.20)

Corrected from:
Controller c300 V3.20
Controller 3200C V3.20
Panel Controller p300 V3.20
Panel Controller p500 V3.20

Response of the new version:
In a PLC application where the current compiler version V3.5.16.20 is set, complete structures or a complete array can be accessed via OPC UA without the OPC UA server stopping.
 
What happens? 
Communication with the OPC UA Server stops. Communication with PLC Designer is still possible.
To reestablish OPC UA communication the controller must be restarted.
 
When does the behaviour occur?
In the PLC application the compiler V3.5.14.40 is set.
A complete structure or array is accessed via OPC UA.
It is possible to access a single structural element or an individual array element.
  
Which products are affected?
Controller c300
Controller 3200C
Panel Controller p300
Panel Controller p500
PLC Designer V3.20
 
Short-term measures:
The compiler of the PLC application must be changed from V3.5.14.40 to V3.5.12.66 (Project --> Project environment --> Compiler version).

Evaluation / Recommendations:
Considering the short-term measure, the functionality is given.
With the controllers c5x0 /c750 this behaviour does not occur.
