I experienced this (non-reproducible) error in a CI run on the pre release (1.11 now), in the MacOS platform:

 ERROR: LoadError: TaskFailedException

    nested task error: InexactError: Int64(1.0)

The line where the error occurred was:

            index = floor(Int, xi) + 1

in which xi is a Float64. As far as I understand, the result of floor should always return an exactly representable Int, so the error should not occur.

When reporting this on Zulip, it, @jlumpe (sorry if the tag is wrong), reported having observed two times similar errors:

https://github.com/JoshuaLampert/DispersiveShallowWater.jl/actions/runs/10811172112/job/29990016675?pr=150#step:7:8511

But these with 1.10.

Thus, although hard to reproduce, might be something worth investigating.
