In case it helps for finding the error, I later noticed that the same bug seems to occur in problem nvs12 (<a href="http://www.gamsworld.org/minlp/minlplib2/html/nvs12.html" target="_blank">http://www.gamsworld.org/<u></u>minlp/minlplib2/html/nvs12.<u></u>html</a>) as well.<br>

Hi, has anyone taken a look at <a href="https://projects.coin-or.org/OS/ticket/55" target="_blank">https://projects.coin-or.org/<u></u>OS/ticket/55</a> ? I’m hitting the same error (even with a recent source build on Linux), Jacobian values are ending up in the wrong columns. The derivative checker in Ipopt is flagging the problem as well.<br>
