lib failure?

[Oliver Block <lists@block-online.eu>]

Hello,

I was facing a problem with a functio I wrote, checking if a file exists 
withing the fs. When I was debuggin that , I set 2 breakpoints, the first to 
the function file_exists and the second to the function call of file_exists 
inside the program. I got the following output

**************************** gdb ************************************
Breakpoint 2, main (argc=1, argv=0xbffff1c4) at ddnscli.c:712
712        if(file_exists(lockfile))
(gdb) s

Breakpoint 1, file_exists (fname=0xbffff110 "disabled") at ddnscli.c:689
689        if( (rval = stat( fname, &attribut)) == -1)
(gdb) s
__stat (file=0xbffff070 "\200", buf=0xbffff070) at stat.c:51
51      stat.c: Datei oder Verzeichnis nicht gefunden.
        in stat.c
(gdb) bt full
#0  __stat (file=0xbffff070 "\200", buf=0xbffff070) at stat.c:51
No locals.
#1  0x0804a56b in file_exists (fname=0xbffff110 "disabled") at ddnscli.c:689
        attribut = {st_dev = 128, __pad1 = 34760, st_ino = 7, st_mode = 53,
  st_nlink = 1075277812, st_uid = 1075283840, st_gid = 134522768,
  st_rdev = 4615200421588234412, __pad2 = 34688, st_size = 40,
  st_blksize = 1075277812, st_blocks = 1073835200, st_atime = 134522768,
  st_atimensec = 3221221564, st_mtime = 1074560382, st_mtimensec = 40,
  st_ctime = 1075277812, st_ctimensec = 3221221592, __unused4 = 1074559989,
  __unused5 = 40}
        rval = 1075277812
*************************************************************************************

__stat (file=0xbffff070 "\200", buf=0xbffff070) at stat.c:51

both arguments of stat hold the same address. file should be AFAIK 
fname=0xbffff110.

I isolated the function to a test_program and it works fine there.

Any ideas?

Regards,

Oliver
