Julia/JuMP crashes in very small model

[Aiko-ewl]

Hey there,

I'm currently working with Julia/JuMP, and this is a strange thing that happens all the time:

I created a very small LP-JuMP model (see below). Whenever I run this model, Julia crashes after a few seconds and advises me to create a bug report with steps to reproduce this bug (see below). Since, it seems to be a jl_compile problem I didn't report it to JuMP so far. However, when extending the code the problem vanishes some times without a reason :/

Looking forward to hear from you :)

Model:

using JuMP, GLPK

phi = [10 30 50]; Q = [80; 60; 40]; x_p = [0 0 0]; x_n = [70 70 70]
H = [ 0.3056 -0.5853 0; 0.3056 0.4147 0; 0.6944 0.5853 0];
H_max = [5 5 5]; G, L = 3, 3;

m = Model(GLPK.Optimizer)
@variable(m, x_n[n] <= x[n=1:G] <= x_p[n] )
@variable(m, y[n=1:G] )
@objective(m, Min, sum(phi*x) )
@constraint(m, con_1[j=1:L], H[j,:]'*y <= H_max[j])
@constraint(m, con_2[j=1:L], H[j,:]'*y >= -H_max[j])
@constraint(m, con_3[n=1:L], (x[n]-Q[n]) == y[n])
@constraint(m, con_4, sum(y) == 0)
optimize!(m)

Which versions of Julia and JuMP is this with? For example, on mac with 1.5.2, it doesn't crash.

Thanks for the quick feedback.

When you mentioned your versions, I found out that there are two Julia versions running on my systems (one in …\AppData\Local\Julia… and one in …\AppData\Local\Programs\Julia…). So I updated my Julia path in the Julia client (via the juno settings in atom). Since then I run my models on Julia 1.4.1 and there is no crash occurring anymore.

Thanks again anyway
