Hi,<br>
<br>
I think that has been fixed already, but has not made it into a release:<br>

If you get the 1.5 stable, then you should get also the bugfix.<br></blockquote><div>Yes this was fixed but not released. Optionally you can just comment the line of code (if you don't want to redownload everything).</div>

The nl input file and the bonmin.opt file are attached. With some others nl<br>
files I have gotten the same error with B-OA algorithm<br>
