OK.  I am glad that this was easy to fix.  Now your task is to figure
out why BINARY_SIZE of 8 did not work - or rather, why it worked for
the self-tests, but not the rest.  And to reduce BINARY_SIZE back to 8
once you figure this out and fix whatever did not support that lower
size.  This ought to work with 8 (with suitable code).

Thanks,

Alexander
