Oh wow pretty big! Can you try calling Gurobi from the cmd prompt? ``` gurobi_cl issue477.mps ``` Can you post the link to the Google Drive file?
Is that for the big original problem that crashes Julia? Hmm. It's going to be hard to find the problem if we can't reproduce via `gurobi_cl`. How much memory do...
> Why "JuMP.optimize!(scuc)" does not work, but "gurobi_cl" does. I don't know. That's the problem! Can you try with all of your options that you had set? ``` gurobi_cl MIPGap=0.002...
Hmm. Did you use `GRBwrite` to make the MPS files? The fingerprints are different > Model fingerprint: 0xf2ca8ff2 > Model fingerprint: 0xfe150f41 Is there any randomness in how you create...
To be able to debug this, we need an MPS file that can trigger the segfault when run via `gurobi_cl`. Of course, if you can reliably trigger that via Gurobi.jl...
One example is ECOS: https://github.com/jump-dev/ECOS.jl/blob/master/LICENSE.md. We include a sentence at the bottom of the LICENSE, but open to suggestions for how this could be improved.
> this worked fine back in v2.10.3 FWIW, Cbc.jl used a patched version of 2.10.3 that meant we never went through Clp for LPs. We're now back on mainline in...
Please provide a minimal working example. How are you calling Cbc?

I can take a look at this today (I think I know what the issue is). Until last week, JuMP was using a patched version of Cbc, which was why...
