Error: unhandled exception: over- or underflow [OverflowError]

I was testing the script disk_usage.nim

When compiled with 64bit it works, however, with 32bit gives the error
/opt/psutil-nim/scripts/disk_usage.nim(34) disk_usage
/opt/psutil-nim/scripts/disk_usage.nim(26) main
/home/kittytechno/.nimble/pkgs/psutil-0.6.0/psutil/psutil_posix.nim(206) disk_usage
