True. But on the other hand, in safety related systems we have
RAM-testing in the background anyhow, so why not also collect some dead
objects during these cycles? - Don't get me wrong, I personally am not
yet convinced, that garbage collection is the best we could do.

When a GC is compiled in, it should at least check locals at function exit. Java and other garbage languages also start the GC at regular intervals in the background, but that means multi-threading.

When a GC is not compiled in, most core libraries try hard not to waste memory. There are a few exceptions: the latest libraries I wrote. I'll have to work on that too (later).

I don't know how wrapped libraries behave when there is a GC or not.

Also note, BDW GC support is still incomplete since the GC at program exit does not work as intended (all objects, including the root object, should be collected and disposed).
