But Shawn and Groepaz are right with one thing: This won't work with the
current library code, because the heap is initialized to start at the end of
the BSS segment and extends to the bottom of the stack, which in turn is
placed at the end of the RAM memory section. And, there is no way to use a
HEAP segment as a general solution (maybe replacing the current one), because
the linker can only handle fixed size segments, while the heap size should
vary depending on the size of the program.
