bug#11316: coreutils 8.16: du |

Hello Paul,
to make tusc-output a little more readable I removed all the syscalls
around lib-loading and gave "du" only a single file:
# ls -als inspection_item.lst
1282246 -rw-r----- 1 xxx xxx 1312994526 Apr 24 01:07
inspection_item.lst
As you can see, HP-UX ls -s outputs 1k blocks while Files on Solaris
NFS-Servers and Files on local Volumes are reported in 512 Byte blocks.
the HP-UX /usr/bin/du does the following:
# tusc -f /usr/bin/du -sk inspection_item.lst
...
open("/usr/bin/du", O_RDONLY, 0)
........................................................................
.... = 3
... (libs read)
open("/usr/lib/hpux32/libc.so.1", O_RDONLY, 0)
.............................................................. = 3
open("/usr/lib/hpux32/libdl.so.1", O_RDONLY, 0)
............................................................. = 3
...
lstat64("inspection_item.lst", 0x40010e40)
.................................................................. = 0
sysfs(GETFSTYP, 0xa, 0x7ffff180)
........................................................................
.... = 0
sysfs(GETFSIND, 0x40010400, 0x288)
........................................................................

sysconf(_SC_CPU_VERSION)
........................................................................
............ = 768
brk(0x400112d0)
........................................................................
..................... = 0
brk(0x400132c0)
........................................................................
..................... = 0
brk(0x40016000)
........................................................................
..................... = 0
ioctl(1, TCGETA, 0x7ffff150)
........................................................................
........ = 0
1282222
write(1, "1 2 8 2 2 2 2 ", 7)
........................................................................
....... = 7
inspection_item.lst
write(1, "\ti n s p e c t i o n _ i t e m ".., 20)
.......................................................... = 20
write(1, "\n", 1)
........................................................................
................... = 1
exit(0)
........................................................................
............................. WIFEXITED(0)
the du on Solaris does "fstatat64()" and afterwards "pathconf(filename,
_PC_XATTR_EXISTS)" to find out more, to return the correct values.
the coreutils-du does:
# tusc -f /usr/local/coreutils/bin/du -sk inspection_item.lst
...
open("/usr/local/coreutils/bin/du", O_RDONLY, 0)
............................................................ = 3

...................................................... = 3

............................................................ = 3
open("/usr/lib/hpux32/libc.so.1", O_RDONLY, 0)

HP-UX has long had problems with 'du', as described in the coreutils
manual. But this particular bug is new.
Can you tell us which system calls coreutils 'du' are invoking, and
which that HP-UX 'du' are invoking, by using the 'tusc' tool of HP-UX?
That might help us isolate the problem.
Here's where I found a download for 'tusc':
