I found a lot of examples by now, where the same problem appears. Here are two of them: (%i1) trigreduce(cos(acos(x)/2)^5*sin(acos(x)/2)^3); Maxima encountered a Lisp error: The value 1 is not of type LIST Automatically continuing. To enable the Lisp debugger set *debugger-hook* to nil. (%i2) trigreduce(cos(acos(sqrt(x^2 + 1))/2)^5*sin(acos(sqrt(x^2 + 1))/2)^3); Maxima encountered a Lisp error: The value -1 is not of type LIST Automatically continuing. To enable the Lisp debugger set *debugger-hook*...
