A test for a number zero in a call to punivarp has been checked in. Maxima no longer gets a fatal Lisp error for the example given in this bug report, but returns an error message: `algsys' cannot solve - system too complicated. -- an error. To debug this try debugmode(true); Closing this bug report as fixed, because Maxima no longer gets a Lisp Error. Algsys is not able to solve the example in this bug report. Maxima does not get more solutions with this fix. See the discussion in SF[1430379] for a suggestion to improve algsys by setting the flag \$algebraic to TRUE.
