<br>
that sounds like a bug to me.<br>
It would be good if you could open a ticket in the bugtracking system about this (login at <a href="https://projects.coin-or.org/Ipopt" target="_blank">https://projects.coin-or.org/<u></u>Ipopt</a>, then New Ticket), including some code snipets about what you tried. Best would be some code to reproduce the issue.<br>

Dear Ipopt Community,<br>
<br>
If I instantiate multiple TNLP instances (with smart pointers and the<br>
IpoptApplicationFactory) that are executed in serial, my program<br>
segfaults. These segfaults seem to go away if I instead create a new<br>
instance of and subsequently delete each TNLP before running the next<br>
one.<br>
<br>
Is this behavior expected even for TNLPs executed in serial? I have<br>
seen warnings against executing multiple TNLPs in parallel, but not in<br>
serial.<br>
<br>
Best regards,<br>
Breannan Smith<br>
