The problem was that I assumed that after a succesful inflate nothing in
my inflate buffer could have gone wrong. But I was actually placed on
the end of that buffer.
So basically protobuf pretends everything is 'ok' and just starts
parsing. So the fix was just nicely to pass the start of the inflated data.
I was coding quite defensive, but it seems protobuf itself still 'eats'
memory. Given the presented 'max 64MB limits', not really an issue, but
it is just duplicating a lot of memory, instead of using pointers to the
For whats worth, currently I'm able to decode the 'fileformat', doing
deflate decompression. So still some stuff to go, but I understand the
basics now... so I'm a happy farmer.
