This problem is with strace-4.3-2.  It is reproducable, and happen
every time.

When running 'strace stat <file/directory>' on RedHat Linux
Advanced Server 2.1AS for ia64, the call to fstat() is not
displayed as it should.

Here are an example of the problematic lines:

  open("/etc/localtime", O_RDONLY)        = 4
  SYS_1212(0x4, 0x60000fffffffb350, 0x10000, 0x3, 0x22,
    0xffffffffffffffff, 0, 0x4) = 0
  mmap(NULL, 65536, PROT_READ|PROT_WRITE,
    MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2000000000354000


The call to SYS_1212() should be translated to something readable
instead, like it is on ix86.  Calls to SYS_1210() have the same
problem.  This make it hard to know what the call to fstat() actually
do.

To reproduce it, just run 'strace stat file | grep SYS_' and look
at the output.

I discovered this while trying to find out why ia64 linux are
unable to properly handle files owned by users with UID > 65k.
I'll report that bug separately when I know more.
