"double free or corruption" when providing duplicate hessian entries via MathOptInterface about ipopt.jl HOT 4 CLOSED

Can you provide a reproducible example?

from ipopt.jl.

Hi, my apologies, while making simplified example for reproduction I figured out that the error was being caused by me accidentally providing out of bounds indices for the hessian structure in my main code, which is my fault. It would be nice though if this threw an error saying as much instead of the segfault.

Thanks!

This can be difficult, because the code is actually getting run from C (hence the segfault and no Julia bounds checking).

In general, I'd encourage you to use JuMP instead of MOI. If you're manually coding the Hessian sparsity and callbacks, it is too easy to make a mistake.

Closing as expected behaviour.
