(%i1) rectform(atan2(y,0));

Division by 0 -- an error. To debug this try: debugmode(true);

In the function risplit a check for a zero denominator is missing.

Fixed in revision 1.37 of rpart.lisp. A check for a zero denominator for the case atan2(y,x) and y/x is a real expression has been added. Closing this bug report as fixed. Dieter Kaiser
