I failed to reproduce infinite looping.
Please attach your .config
Wrong cksum for files > 4 Gb is fixed by attached patch, please confirm.
It works for me. Comparison with coreituls:
# dd if=/dev/zero bs=1M count=9999 | ./busybox cksum
9999+0 records in
9999+0 records out
992689976 10484711424
# dd if=/dev/zero bs=1M count=9999 | /usr/bin/cksum
9999+0 records in
9999+0 records out
