ecrt_domain_reg_pdo_entry_list() stores the offset of the Pdo entry in
the domain's process data into r_dig_out since version 1.4, not the
address of the data (see list of changes in ecrt.h), so you'll have to
add the domain data offset to r_dig_out (like done in the minimal
example).

Sorry I did not manage to port the RTAI example up to now. The pdf
documentation will also get a complete update for the 1.4 release.
