CI jobs are failing

[jishnub]

Looking at the recent runs, the docs job (e.g. https://github.com/JuliaLang/LinearAlgebra.jl/actions/runs/13954106194/job/39060797306?pr=1245) fails with a ProcessSignaled(11), as do the buildkite jobs (https://buildkite.com/julialang/linearalgebra-dot-jl/builds/367#0195afad-9bf0-4e14-8043-b5d765b9ca8d) which fail with a ProcessExitedException.

@KristofferC said this might be due to the lazy jll stuff. cc @staticfloat

I'm saying that based on that CI here was never tested with the Base changes to lazy jlls. As far as I see, the CI status when the lazy jll stuff was merged is https://buildkite.com/julialang/linearalgebra-dot-jl/builds/350#01958fe7-8323-4afb-af81-fa1467b814eb

which errors straight away with

Failed to precompile LinearAlgebra [37e2e46d-f89d-539d-b4ee-838fcccc9c8e] to "/cache/julia-buildkite-plugin/depots/01933eb6-fbbe-448a-b4d9-f85a2cf4879d/compiled/v1.13/LinearAlgebra/jl_Ce3cee" (ProcessExited(1)).

I'm AFK right now, but looking into the failing jobs I see:

Test Failed at /cache/build/tester-amdci5-8/julialang/linearalgebra-dot-jl/test/matmul.jl:328
  Expression: 0 == #= /cache/build/tester-amdci5-8/julialang/linearalgebra-dot-jl/test/matmul.jl:328 =# @allocations(mul!(C, transpose(A), A))
   Evaluated: 0 == 1

Which is exactly the issue I was trying to solve in 1ce8426. Perhaps my fix is incomplete somehow. It is interesting that the macos-aarch64 job passed there.

That's not the issue. This is the issue https://buildkite.com/julialang/linearalgebra-dot-jl/builds/377#0195e5fe-f561-4369-b6ff-6fcdb72a05d4
