Adding in -s this is part of what I see:

TFTP from server 192.168.0.3; our IP address is 192.168.0.140

Bytes transferred = 1048576 (100000 hex)
=> crc32 80000000 $filesize
CRC32 for 80000000 ... 800fffff ==> F2fa737e0

For some reason there's an extra 'F' at the start of the crc32 output.
Looking at it in the html file, it looks all correct there.  In the
output from test.py the captured stdout end just before the CRC32 value
would be.  I've tried larger test binaries and get the same output so
I'd assume if there was some heap corruption or similar, I'd not tickle
it with bigger files too (2MiB, 4MiB and I think even 8MiB are small
enough to be downloaded in the time the test allows).  Thanks!
