Bug#1053090: libxsimd-dev: arm64 error in xtensor: usage of batch type with unsupported type

Package: libxsimd-dev
Followup-For: Bug #1053090
Control: reassign 1053090 libxtensor-dev
Control: forwarded 1053090 https://github.com/xtensor-stack/xtensor/issues/2733

xsimd upstream https://github.com/xtensor-stack/xsimd/issues/945 
identified the problem that neon64 does not support bool.

A minimal test case using xtensor only was found:

#include <xtensor/xtensor.hpp>

int main()
{
    {
        xt::xtensor<double, 1> a{0., 1.};
        xt::xtensor<double, 1> b = a && 0.;
    }

    {
        xt::xtensor<bool, 1> a{false, true};
        //xt::xtensor<bool, 1> b = a && false;
    }

    return 0;
}


That contains the problem inside xtensor, so transferring this bug to
the xtensor package.
