Thank you! I will mark this case to be handles as a TODO for later then. I have
worked today so far on you suggestion:

What I have done: I have run the current implementation on a test file that
does return by value and indeed there is no MemRegion for it, so the checker
silently skips it and proceeds. I have rewritten the Program State Map to
`SVal` as the key instead of `MemRegion` and updated the `set` calls to work
with it.
I have some build issues that I want to figure out now, but once I can resolve
it I will push my changes.
