gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)
strace output from stat call: if(stat(fname.c_str(), &results) == 0) {....
stat64("/home/steverex/isofiles/news34.tar",{st_mode=S_IFREG|0664,st_size=3698647040,
...}) = 0
you got a 3.699GB file properly statted
(gdb) print results (print the user space structure returned from call)
$58 = {st_dev = 772, __pad1 = 0, st_ino = 8257539, st_mode = 33204, st_nlink =
1, st_uid = 500, st_gid = 500, st_rdev = 0, __pad2 = 0, st_size = -596320256,
st_blksize = 4096, st_blocks = 1370856, st_atim = {tv_sec = 1123814216,
tv_nsec = 0}, st_mtim = {tv_sec = 1123741947, tv_nsec = 0}, st_ctim = {tv_sec =
1123741947, tv_nsec = 0}, __unused4 = 0, __unused5 = 0}
returned st_size is negative due to unsigned long restriction in kernel_stat.h
return error is genn'd from xstat32_conv in xstatconv.c
I looked for missing config/ifdefs etc. I did trace glibc flow from (abbr):
xstat,i686.get_pc_thunk.bx,xstat,xstat32_conv,i686.get_pc_thunk.bx,xstat32conv,xstat,ret
