Hello,
     I use debian sarge for alpha processor.
My installation contains coreutils 5.2.1 and I note
that du utility doesn't count correctly disk usage
for directory over 4GB.

For example I have a directory sarge-20041016
that contains a DVD iso image. The output of
"ll" is the following and it reports fine filesize.

alpha:/mnt/sdd2# ll sarge-20041016
total 4544832
-rw-r--r--  1 tullio tullio 4653907968 Oct 16 05:10 sarge-alpha-1.iso

If I type du, I see the following output
alpha:/mnt/sdd2# du -s *
350528  sarge-20041016     <--- du displays only ~ 350MB
alpha:/mnt/sdd2#

So I searched in coreutils source file where du calculates used space
and I have tried this simple solution:
--- coreutils-5.2.1/src/du.c.orig       2005-03-22 23:22:58.740931368 +0100
+++ coreutils-5.2.1/src/du.c    2005-03-23 12:56:36.854330472 +0100
@@ -382,7 +382,7 @@
     {
       size = (apparent_size
              ? sb->st_size
-             : ST_NBLOCKS (*sb) * ST_NBLOCKSIZE);
+             : (uintmax_t)ST_NBLOCKS (*sb) * ST_NBLOCKSIZE);
     }

   if (first_call)



I think the real problem is * operation that exceed some 32 bit wide type.
On my alpha system sizeof returns:
   sizeof(int)=4 byte
   sizeof(long)=8 byte
   sizeof(long long)=8 byte
   sizeof(uintmax_t)=8 byte

Thanks,
   tullio
