I'm not able to verify this. A short program using the start attribute shows
the expected behaviour. Can you please send me a short(!) but complete(!)
program that enables me to reproduce the problem?

The linker will relocate the date that it runs in the given memory area, but
it will not place it there. If your data is not part of the actual program
(for example, because it must be loaded elsewhere), it is your responsibility
to move the data to this location.
