C++ 20 Ubuntu axis_slice_iterator bad alloc exception

[spectre-ns]

The following code compiled with GCC 11.3 using C++20 throws on the following code snippet

        xt::xarray<double> savgol_filter(xt::xarray<double> x, size_t window_length, size_t polyorder, std::ptrdiff_t axis = -1)
        {
            xt::xarray<double> out = xt::empty_like(x);
            auto saxis = xt::normalize_axis(x.dimension(), axis);
            auto begin = xt::axis_slice_begin(x, saxis);
            auto end = xt::axis_slice_end(x, saxis);
            auto iter_out = xt::axis_slice_begin(out, saxis);

            SavGolTransform filter(x.shape(saxis), window_length, polyorder);
            std::vector<xt::xarray<double>> res;

            for (auto iter = begin; iter != end; iter++)
            {
                *iter_out = filter.Transform(*iter);
            }

            return out;
        }

The same code runs in windows and macos in CI. Oddly only fails in Ubuntu. The following line appears to be the culprit:

                *iter_out = filter.Transform(*iter);

I'm trying to apply a function along a particular axis and hopefully this is not a dumb way to do it.
