    -Hi,
    -
    -Out of curiosity, I tried this in maxima 5.45.1:
    -
     (%i1) integrate(sin(tan(x)), x);
    -
    -It responded with an error message:
    -
     PDIVIDE: Quotient by zero
      -- an error. To debug this try: debugmode(true);
    
    -Looks like a bug to me.

    No longer results in an error, but a noun form. I guess that's OK.
