The program just works:

[ Process PID=8968 runs in 32 bit mode. ]
uname({sys="Linux", node="xen-to1", ...}) = 0
brk(0) = 0x80c3000
brk(0x80c3cb0) = 0x80c3cb0
set_thread_area(0xffa5182c) = 0
brk(0x80e4cb0) = 0x80e4cb0
brk(0x80e5000) = 0x80e5000
fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xfffffffff7f51000
write(1, "Hallo Welt!\n"..., 12Hallo Welt!
) = 12
