It also works fine on a x86_64 machine in 32 bit mode. > So the questions is to cygwin developers: what can be done next?

No, because this would also exclude x86_64 machines. Actually I'm somewhat in doubt that CreateFileMapping/MapVieOfFile functionality should actually be so broken on the ia64 platform. Are you really sure that the culprit isn't somewhere else? Your test application uses a very common idiom, so I'd guess that a lot more applications would fail miserably on ia64 in 32 bit mode.
