Sergey,
please consider applying these patches:
$ dd if=/dev/zero of=/tmp/big bs=1M count=4500
$ find /tmp/big | ./cpio -o > archiv.cpio
cpio: File /tmp/big grew, 0 new bytes not copied
827393 blocks
after patch cpio-largeFileGrew.patch is applied
$ find /tmp/big | ./cpio -o > archiv.cpio
./cpio: /tmp/big: field width not sufficient for storing file size
1 block
$ echo $?
0
after patch cpio-toAsciiError.patch is applied
$ find /tmp/big | ./cpio -o > archiv.cpio
./cpio: /tmp/big: field width not sufficient for storing file size
$ echo $?
1
and that seems to be alright for me.
cpio was compiled on i386 with -D_FILE_OFFSET_BITS=64
-D_LARGEFILE64_SOURCE
