i didnt even know that we shipped this tool.
i would set it
D4/W1/I5, especially note the I-value, 
why would *anyone* use this tool now that we have print-functionallity in ndb_restore

i think we should just remove the tool from the distribution and say "won't fix" on this (but keep the code for debugging only purposes)

however if we anyway decide to fix it, i would say
R1, E3

      ndb - ndb_print_backup - bug#48673, bug#41512 - adopt to azio changes
[9 Mar 2010 15:27] Jonas Oreland 
pushed to 6.3.33, and 7.0.14
[10 Mar 2010 9:30] Jon Stephens 
Documented fix in the NDB-6.3.33 and 7.0.14 changelogs as follows:

        The ndb_print_backup_file utility failed to work, due to a
        previous internal change in the NDB code.

Closed.
