I did reproduce the problem on x86 full 32 bits... So it's seems that
the bug has always been present on 0.8.3. It is unclear how it slipped
through as bb_simu + tsp_bb_provider + tsp_stdout_client is a classic
test combo.

I didn't take time to dig deeper, but the cause of the problem in
tsp_data_sender is that dimension is 0, so the encoder correctly
returns 0.

Just in case, I've uploaded a tarball of latest CVS here:
http://www.xprog.eu/tsp.tgz . Could you have a look Olivier?
