That's odd, on my system this syntax fails to link.

$ clang -c -o hello.o -arch i386 hello.s
$ ld -o hello -macosx_version_min 10.6 -arch i386 hello.o
$ ld: section __data (address=0x00002000, size=4294967279) would make the
output executable exceed available address range for architecture i386

Joerg, could you post a full hello.s file?

What are your system specs? Mine are:

$ ld -v
