[Bug-gnubg] Bug in bearoffdump?

[isambard mews]

I tested out bearoffdump on a test database using normal distribution format and got the following strange output (running on a 64bit Debian system). I was expecting a similar format to a non-ND database and wonder if this is a bug:

$ bearoffdump -n 56 ntest_osx2.bd 

Bearoff database: ntest_osx2.bd

Position number : 56

Information about database:
