Jesse,

Good points. This leads to another question: How would one go about setting up a project with a memory map (for the RAM area, at least) as follows:

(Low Memory)

vectors

text segment

data segment

bss segment

stack (fixed maximum size, grows down)

heap

(High memory)

In this case, could the heap size be set at runtime? Failing that, could the upper heap limit be initialized to a point representing minimum-installed memory, which could then be moved up when more memory was detected?

Just some thoughts.
