libhpcalcs: portable (Windows / MacOS X / Linux) connectivity kit library

I found another problem, if I try to receive a file that is bigger then I got this error,

hpcalcs DEBUG: Dumping IN packet with size 64
hpcalcs DEBUG: 00 74 00 6F 00 20 00 69 00 74 00 73 00 20 00 73

hpcalcs ERROR: calc_prime_r_recv_file: CRC mismatch
hpcalcs_calc_recv_file finished
Receive file success

That seems to happen on all files that are bigger than maybe 2KB.
I have used the latest code from git.
Is there anybody else that got this error on bigger files? I run on a Mac
