 -- an error. To debug this try: debugmode(true);

observed in wxMaxima 14.12.1. No problem for small x.

What version of maxima? (Use build_info() to find out).

I don't have this problem with tip of tree version with cmucl. The result is about 0.92867.

build_info(version="5.29.1",timestamp="2013-01-23 09:18:19",host="i686-pc-linux-gnu"
,lisp_name="SBCL",lisp_version="1.0.55.0.debian")

Then the problem obviously has been fixed in the meantime.

Ah, it looks like it was fixed in bug #2999.

Closed as fixed.
