Hi there,
We frequently check the correctness of memory management in Ipopt. We use
the free GNU tool 'valgrind' for this. Since you also seem to use Linux,
I suggest you run your application (compiled with debug code) with
valgrind to see where the memory is being messed up; if it is in your code
or in the Ipopt code. (I'm assuming there that you are not using AMPL,
but that you wrote your NLP formulation in some programming language and
interfaced with the Ipopt library...?).
If the first memory error shown by valgrind is indeed in the Ipopt code,
please attach the valgrind output to this ticket.
Thanks
Andreas
