The Linux kernel ACPI interpreter fails the following

Created attachment 6257 [details]
ASL code to reproduce bug.

The Store operations of demo program attempt to rewrite
the contents of the target objects of RefOf references
passed immediately to the Store operations as a return
of some Method call. The following verification shows
that in fact the target objects are not changed.
That is considered as errors.

One of choices for Destination of Store operation
"Store(Source, Destination)" is a call to Method:
SuperName->Type6Opcode->UserTermObj-><NameString TermArgList>
