tadeja opened a new pull request, #50705:
URL: https://github.com/apache/arrow/pull/50705
### Rationale for this change
Fix #50636 - `test-r-macos-as-cran` nightly job fails compiling
`visit({range_start, range_cur})` introduced in #50248.
```console
/Users/runner/work/crossbow/crossbow/arrow/cpp/src/arrow/compute/kernels/vector_sort.cc:325:11:
note: candidate function not viable: cannot convert initializer list argument
to 'std::span<uint64_t>' (aka 'span<unsigned long long>')
325 | [&](std::span<uint64_t> indices) { SortNextColumn(indices,
offset); });
```
The job pins [macOS SDK
11.3](https://github.com/ursacomputing/crossbow/actions/runs/30420027426/job/90474737457#step:9:14),
so libc++ there does not have C++20 iterator-pair span constructor available
yet ([available with libc++ 14](https://libcxx.llvm.org/Status/Cxx20.html)).
Similar problem as in recent #50295
### What changes are included in this PR?
Replace std::span iterator-pair constructor with subspan in `vector_sort.cc`
### Are these changes tested?
Yes, builds locally and will verify `test-r-macos-as-cran` via crossbow.
### Are there any user-facing changes?
No.
