I reopened the issue, but it is still possible that the problem has been fixed (directly or indirectly) in the main development branch. For example, https://github.com/scipy/scipy/pull/15763 made significant changes to...

Thanks @BrentTanKian, that sounds good. We generally don't assign issues, so you can go ahead and work on it.

This was fixed by https://github.com/numpy/numpy/pull/22309.

Given the signature searchsorted(a, v, side='left', sorter=None) the function could be implemented as a wrapper around two (private) gufuncs: gufunc shape signature ---------------------------------------------- ----------------- _search_sorted(a, v, side) (n),(),()->() _search_sorted_with_sorter(a, v,...

This appears to have broken some tests in `scipy.sparse`. Ultimately, the problem comes down to the dtype check requiring that the dtypes are the *same object*, instead of being equal...
