Attachment: trac-6025.patch.gz

As William pointed out on the mailing list, this code isn't used anywhere -- so we're just killing the function. The problem is that on 64 bit OSX, a value getting returned loses its top 4 bytes. This is clearly weird, but since this pari function is known to be buggy, we'll just not use it for now and cross our fingers.
