The current implementation of the heap assumes that the stack is located at
the end of the BSS segment. The heap is located at the bottom of the stack and
will grow downwards. There has been a discussion about changing this some
months ago, but a flexible solution requires expressions in the linker
scripts, so it has been postponed.
If you want to change the current behaviour, you will have to replace the heap
initialization code in the _heap.s module.
