[Ipopt] Memory Error

[Victor Evangelista]

Hi,

I'm trying to use Ipopt to solve a nonlinear optimization problem using the "limited-memory" option for the "hessian_approximation" parameter and I'm getting a "double free or corruption (!prev)" error. I'm not sure if there is something wrong on the implementation of my model, so I'm coming here for help, thanks in advance. Below is the backtrace of gdb:
