Greetings to all -
With maxima 5.29.1 I find the following bug:
(%i1) int1:z*(1-z)*log(1-a^2*z*(1-z));
2
(%o1) log(1 - a z(1 -
z)) (1 - z) z
(%i2) integrate(int1,z,0,1);
subst: cannot substitute - z for operator z in expression z(1 - z)
-- an error. To debug this try: debugmode(true);
(%i3) int1:z*(1-z)*log(1-a^2*z*(1-z));
2
(%o3) (1 - z) z log(1 -
a (1 - z) z)
(%i4) integrate(int1,z,0,1);
Is a positive or negative?
p;
Is a - 2 positive or negative?
n;

Many thanks,
