Still some failing tests for eig_trunc!. It seems to be a tolerance issue, since the failing comparisons are actually not too bad:

Expression: diagview(D4) ≈ (diagview(D))[1:2]
   Evaluated: ComplexF32[0.89972997f0 + 0.0f0im, 0.30034363f0 + 0.0f0im] ≈ Float32[0.9, 0.3]

and

  Expression: ≈(ϵ3, norm((diagview(D))[3:4]), atol = atol)
   Evaluated: 0.10009178f0 ≈ 0.10049876f0 (atol=0.00034526698)

The first one doesn't seem to have a tolerance specified, so maybe that is fixed by adding the current default. The second one seems fine if the tolerance were just a little bit bigger, so maybe a factor 2 extra would be good.

It's odd that it only happened on Windows... I'll look further

That's a random number effect I think. Though it is often on Windows it seems. I guess that OS has some special affinity for bugs 😄 .

Should this not also be changed for the lq tests?

[kshyatt]

I think it was already fixed there?
