Some software may work perfectly on x32 while barfing on x64, especially software that wasn't designed with x64 in mind. Making software compatible with every conceivable architecture upgrade of the distant future would add massive layers of abstraction.
Many years ago, while taking a C programming course, I ran into some "gotchas" with variable sizes, when moving between 32 & 16 bit systems. In class, we were using Borland's Turbo C++ for DOS and at home I had Borland C++ for OS/2. There was a difference in the size of some variable types, such as INT, so that a program that ran fine at home would fail in class, because I had exceeded the maximum integer size. However, I have no idea how 32 & 64 bit systems compare with this issue.
It's still the exact same thing. People are not making architecture independent code, still. -- Mads Martin Joergensen, http://mmj.dk "Why make things difficult, when it is possible to make them cryptic and totally illogical, with just a little bit more effort?" -- A.
