Oops. I can reproduce this. This is fixed in the latest snapshots;
I'm not sure the cause of this error right now, and don't want to look
into it since the snapshots don't have this problem. Is 19a a
requirement?
Also, cmucl doesn't have specialized complex number for fixnums. It
only supports (complex rational), (complex single-float), and (complex
double-float).
