I got a software understanding where such a variable can not be obtained
from this function call.
The return value (like a pointer in this use case) can be stored there.

The support for data type casts is another interesting extension for
this source code analysis approach.
Further adjustments might become possible at other places of the presented SmPL script
after specific clarifications of previously mentioned implementation details.
