I tried using Cbc and JuMP but get a double free error on an M1 macbook pro: ``` julia> using Cbc julia> using JuMP julia> model = Model(Cbc.Optimizer) julia(6797,0x100a88580) malloc:...

Cbc ignores parameters when model is an LP

Cbc ignores the outcome of `set_silent` when the model is an LP. I guess this is because the attribute isn't passed to CLP. MWE: ```julia using JuMP, Cbc Cbc_optimizer =...

When I provide a custom start value for some of my variables via JuMP, then the solver crashes with segfault and/or double free errors. I can only reproduce for indicator...

SOS constraints without integer variables

2

I tried enabling indicator tests: https://github.com/jump-dev/Cbc.jl/blob/01ee423efa84f3cad38e4973b5f578915c69e181/test/MOI_wrapper.jl#L77 but it fails as Cbc believes the problem to be unbounded. The indicator constraints are bridged by the [IndicatorSOS1Bridge](https://jump.dev/MathOptInterface.jl/v0.9.19/apireference/#MathOptInterface.Bridges.Constraint.IndicatorSOS1Bridge) into SOS1 constraints. This issue...
