This failed on i686 only. There was a single test failure, which it looks like is actually just a negligible rounding/precision discrepancy.

        Raises an AssertionError if two objects are not equal.
    
        Given two objects (scalars, lists, tuples, dictionaries or numpy arrays),
        check that all elements of these objects are equal. An exception is raised
        at the first conflicting values.
    
        When one of `actual` and `desired` is a scalar and the other is array_like,
        the function checks that each element of the array_like object is equal to
        the scalar.
    
        This function handles NaN comparisons as if NaN was a "normal" number.
        That is, AssertionError is not raised if both objects have NaNs in the same
        positions.  This is in contrast to the IEEE standard on NaNs, which says
        that NaN compared to anything must return False.
    
        Parameters
        ----------
        actual : array_like
            The object to check.
        desired : array_like
            The expected object.
        err_msg : str, optional
            The error message to be printed in case of failure.
        verbose : bool, optional
            If True, the conflicting values are appended to the error message.
    
        Raises
        ------
        AssertionError
            If actual and desired are not equal.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.

It currently FTBFS very early on, on x86-64, because of removal of distutils:

Upstream build system is slightly deranged.  They have removed 'setup.py' which
we are using:

https://github.com/scipy/scipy/commit/e8d73fa4741be67dd4329f56f400e45fd37f3fc1
https://github.com/scipy/scipy/commit/03dc21068e9a53d915a8acd36da1333e0a61bdd0

There's a meson-based build system which is hopeful, but I don't really have any
clue about how we'd go about using it.

There is an open PR that takes care of the build system changes:
