gp: mulscalrfrac() bug 

pari-dev,

In basemath/gen1.c:912 is the line :

    if (lgef(d) == 3) return gerepileupto(av, gdiv(gmul(x,n), (GEN)d[2]));

which fails in gdiv() with :

  ***   incorrect type in inverse.

for example :

? s0=u;s1=v;s2=-s0+s1/(1-s1^2)/t;s2/(1-s2^2)/t-s1
  ***   incorrect type in inverse.

which used to work until recently. Shalom, Michael
