Hi all,
I am using Julia through Juno/Atom on a Mac, and got the following error today
I can run my code through the terminal through. I am not sure what’s going on here. Any suggestions? Thanks.

Let’s just use one topic for this. Given that you can run your code outside Juno, and given that there’s a known rogue segfault in Juno right now, let’s use that thread.

> Hi all. I am using Julia through Juno on a Mac, and got the following error today when I was trying to call the optimize! function from JuMP using JuMP, Ipopt m\_test = Model(with\_optimizer(Ipopt.Optimizer, linear\_solver = "ma57")) @variable(m\_test, x[i in 1:10], lower\_bound = 0.0, upper\_bound = 1.0) @constraint(m\_test, sum(x) == 1.0) @objective(m\_test, Min, sum(i \* x[i] for i in 1:10)) JuMP.optimize!(m\_test) I can run my code through the terminal though…
