infinite recursive loop in dereferencePtr()

[nitram509]

Found by Gemeni ...

Issue Description

The dereferencePtr function follows pointers indefinitely using a for loop. If a value is a circular pointer (e.g., a pointer that points to itself), the function will loop forever, hanging the process. This can be triggered via the get value FEEL function if the provided context contains such a structure. This represents a potential Denial of Service (DoS) vulnerability.
