I don't know TP, but it might very well be that stack and (local) heap have to share a 64 kB (DGROUP) segment in both real- and protected-mode.

However, it should be possible to additionally create "far heaps", which are not limited to 64 kB - I guess this should be possible in both real- and protected-mode. Of course, "far heaps" will return FAR ( == 4 byte ) pointers.
