When the block size * block count equals to 2gb or more, afio corrupts the
archive by truncating all files larger than 2gb.

Thanks for the bug report and patch, I am reviewing and incorporating it in the upstream.

The patch upgrades some uints to size_t, but it does not upgrade the count argument of readall to size_t, so I think this might lead to the achive ending up corrupt because not all data is written into it if your memory buffer (size * block count) is over 4GB and the file being archived is over 4 GB. I am not entirely sure, I have not tested it to verify, but just a warning: if you upgraded to 4GB memory buffer you might have gotten corrupt archives.
