Probably, because there was a "design rule" or "base statement" for C++, that the intent is to make no room for anything else than assembly below it? BTW those few wasted bytes may just mean out-of-luck situ on an embedded system. Because we do not talk about few wasted bytes, but few wasted bytes _everywhere_! And what, if the system has some special HW (like matrix/vector/whatever) with a special floating point[array] type... and that has to be aligned to 8K page bounday? Will you actually allocate 3 integers padded up to 8K? Attila [ Send an empty e-mail to c++-help@netlab.cs.rpi.edu for info ] [ about comp.lang.c++.moderated.
