Hi,
I noticed 64-bit tar incorrectly creating symlinks, and isolated this to
this testcase:
---
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
struct stat sb;
int fd = open("foo", O_RDWR | O_CREAT, 0666);
if (fd < 0)
abort();
if (fstat(fd, &sb) < 0)
abort();
printf("%lu.%lu\n", sb.st_mtim.tv_sec, sb.st_mtim.tv_nsec);
if (stat("foo", &sb) < 0)
abort();
printf("%lu.%lu\n", sb.st_mtim.tv_sec, sb.st_mtim.tv_nsec);
if (fstatat(AT_FDCWD, "foo", &sb, 0) < 0)
abort();
printf("%lu.%lu\n", sb.st_mtim.tv_sec, sb.st_mtim.tv_nsec);
return 0;
}

Compile with -m64. The problem does not show up with -m32.
Linux ares 2.6.32 #16 SMP Sat Dec 5 21:02:04 CET 2009 sparc64 sparc64
sparc64 GNU/Linux [sun4v]
This testcase will print, for example:
1260745109.0
1260745109.876573675
1260745109.876573675
So on a quick glance, fstat64 looks broken.
I am trying to look at it further, but I hope you can beat me to it ;-)
