You found a bug in the C library's file reader code; I've opened up a bug report for it:


The problem is that the file reader code isn't propagating errors correctly up through the
call stack; which makes avro_file_reader_read not detect EOF; which makes you loop through
the final block of the file twice.  That's where the extra 30 records in your count comes
from — in the file you're reading, the final block must contain 30 records.

I've got a patch ready for this; I'll test on a couple of platforms and then commit it to
