Build fails with clang 19.x

[emmenlau]

There are some build errors with clang 19.1.0-rc3. Not going into details, as this seems just untested right now.

Confirming that xtensor builds fail with Clang 19 stable.

Confirming that xtensor builds fail with Clang 19 stable.

Just for curiosity, can you share more details what you tried? What versions of xtl, xsimd, xtensor? What version of clang? And what OS?
