Track failures on nightly #3752

Closed odow closed 1 month ago

odow commented 1 month ago

Nightly is failing in https://github.com/jump-dev/JuMP.jl/pull/3751:

https://github.com/jump-dev/JuMP.jl/actions/runs/9166022620/job/25200626850?pr=3751

The usual culprits: changes to LinearAlgebra and handling around zero and #undef elements.

Upstream is likely https://github.com/JuliaLang/julia/pull/52730

odow commented 1 month ago

We might need to implement appropriate LinearAlgebra.haszero(::Type{AffExpr}) = true

May also be fixed by https://github.com/JuliaLang/julia/pull/54529

odow commented 1 month ago

Closed by #3753. We could revert if this is fixed upstream.
