Replying to [comment:4 rws]:
> Which code would that be? Have you tried callgrind? I tried to confirm
the random behaviour of the above but the first 16 tries all gave False.
Do you have a reliable example?
Could you try it with the following expression? This is the original one
which brought me to this error. If it works (which is rarely; maybe one
out of 20 times on my laptop here), it takes several seconds.
{{{
sage: bool(gamma(2 + k*pi*I/log(2)) * zetaderiv(1,
1+k*pi*I/log(2))/log(2)^10 == 0)
}}}
