This change seems to be the cause (which was motivated by the fact
that otherwise with large memory model regular malloc's would fail as
they bumped into the allocated memory block)

if I change it back to 0 it's ok. The large memory model is only used
for debugging though ... I am still puzzled as to why last-fit
allocation seems to cause memory corruption (with small model here!)
and first-fit does not.
