This closes numpygh-28190 and fixes another issue in the initial code that triggered the regression. Note that we may still want to avoid this, since this does lead to constructing (view compatible) structured dtypes unnecessarily here. It would also compactify the dtype. For building unnecessary dtypes, the better solution may be to just introduce a "canonical" flag to the dtypes (now that we have the space).

replace it -> replace dtype (since "it" could also refer to ap2, the array).
Actually, with my comment below, I think this can just be
/* need ap2 as contiguous array and of right dtype (note: steals dtype reference) */

Combine with l.2162? And write there,
/*
* The dtype reference we had was used for creating ap2, which may have
* replaced it with another. So here we copy the dtype of ap2 and use it for `ap1`.
*/
dtype = (PyArray_Descr *)Py_NewRef(PyArray_DESCR(ap2));

Might as well get this in, I think! |

Actually, the bug may be going back to when the
_intversion was added (and started using borrowed references rather than stealing). Somehow, it seems we got away with that for a suprisingly long time.
