[Bug 459548] [NEW] Error: Can't open directory "blah" (stat() returns -1)

[Joel]

Public bug reported:

Binary package hint: tagtool

Expected: tagtool would load up a list of mp3's from the specified
directory.

Actual:

tagtool failed to open a cifs mounted directory.
It failed with the message: 'Error: Can't open directory "/mnt/Music" '
The stat call in file_list.c:check_working_dir() fails with a return value of -1.

I was able to get it to work by using the following steps:
1. apt-get build-dep tagtool
2. apt-get source tagtool
3. cd tagtool-0.12.3
4. CFLAGS="-D_FILE_OFFSET_BITS=64 -g" ./configure && make && make install

I have a directory mounted using cifs from fstab.
The fstab entry looks like this:
//192.168.1.2/Music /mnt/Music cifs rw,username=SomeUser,credentials=/root/.smb_creds,uid=1000,gid=1000,file_mode=0755,dir_mode=0755 0 0

The cifs server is a window home server box (essentially windows server
2003 sp2).

aptitude show tagtool

And here is a gdb session using CFLAGS="-D_FILE_OFFSET_BITS=64 -g":
Breakpoint 1, check_working_dir () at /usr/include/bits/string3.h:99
99	  (void) __builtin___memset_chk (__dest, '\0', __len, __bos0 (__dest));
(gdb) n
311		res = stat(working_dir->str, &stat_data);
(gdb) set print pretty
(gdb) info locals
res = 0
stat_data = {
  st_dev = 26, 
  __pad1 = 0, 
  __st_ino = 797, 
  st_mode = 16877, 
  st_nlink = 1, 
  st_uid = 1000, 
  st_gid = 1000, 
  st_rdev = 0, 
  __pad2 = 0, 
  st_size = 0, 
  st_blksize = 16384, 
  st_blocks = 0, 
  st_atim = {
    tv_sec = 1256353883, 
    tv_nsec = 640250000
  }, 
  st_mtim = {
    tv_sec = 1256246783, 
    tv_nsec = 952750000
  }, 
  st_ctim = {
    tv_sec = 1256246783, 
    tv_nsec = 952750000
  }, 
  st_ino = 71494644084507421
}

Notice that stat_data.st_ino is clearly larger than uint32
