[CI] Tests are failing

[amontoison]

I suspect that the culprit is the new release of METIS.jl.

[dpo]

The error occurs in a test that doesn’t use Metis I think:
https://github.com/JuliaSmoothOptimizers/LimitedLDLFactorizations.jl/blob/main/test/runtests.jl#L173

Here is the error:

test in-place version: Test Failed at /home/runner/work/LimitedLDLFactorizations.jl/LimitedLDLFactorizations.jl/test/runtests.jl:173
  Expression: allocs == 0
   Evaluated: 48 == 0

We should try wrap these unit tests in functions. I remember that extra bits where allocated in the tests of Krylov.jl because of the scope of the variables.

@geoffroyleconte May I ask you to have a look?

[dpo]

It’s odd because the same code in a function run with —track-allocations reports exactly zero allocations. So it has to do with the tests themselves.

[amontoison]

Ok, so you almost confirmed that the culprit is the global scope.

[dpo]

In Krylov.jl, the tests are not in functions though … 🤔

[amontoison]

If I update the Project.toml such that AMD = "=0.5.0", I don't have the error anymore.

I mixed things up... It was for older versions of Julia that I wrapped the Krylov tests in functions.

Please submit a PR.

[amontoison]

We need to solve the problem first, I don't know why the version 0.5.1 of AMD.jl introduced some allocations.

[amontoison]

I found the culprit.
