<pre>With recent Clang:
(0.0+1.0*I) / (0.0+0.0*I) gives -nan + inf i
(inf+nan*I) / (0.0+0.0*I) gives nan + nan i
(inf+0.0I*I) / (0.0+0.0*I) gives inf + -nan i
The first and third cases look correct. The second yields the wrong answer due
to PR8532; the problem is that nan * I gives nan + nan i because I has type
_Complex double, not _Imaginary double. However, given a nanI which is 0 + nan
i:
(inf+nanI) / (0.0+0.0*I) gives inf + nan i
So I think this is now fixed. (Please reopen if the above don't look like the
right infinite values for these cases.)</pre>
