The HEAP starts at the end of the DATA section and grows upward.
The STACK starts at the end of the RAM and grows downward.
The HEAP and stack STACK are only checked at compile time:

This is just a check for the bare minimum for the Heap+Stack area before
aborting compilation, it is not the run time limit:
