I tested this on 4.8 and all of the 5.0 betas I have around. This is on
an 8-core Xeon machine running Ubuntu 12.04 (but the binaries were built
when it was 10.04):
drake@sagenb:~/s$ for d in sage-* ; do echo -n $d && $d//sage -c
"x=var('x');print integrate(ln(1+4/5*sin(x)), x, -3.1415, 3.1415)" ; done
resulted in
sage-4.8: integrate(log(4/5*sin(x) + 1), x, -3.1415, 3.1415)
sage-5.0.beta1: integrate(log(4/5*sin(x) + 1), x, -3.1415, 3.1415)
sage-5.0.beta2 integrate(log(4/5*sin(x) + 1), x, -3.1415, 3.1415)
All these failed:
sage-5.0.beta3
sage-5.0.beta4
sage-5.0.beta5
sage-5.0.beta6
sage-5.0.beta7
sage-5.0.beta8
sage-5.0.beta9
sage-5.0.beta11
sage-5.0.beta12
sage-5.0.beta13
sage-5.0.beta14
sage-5.0.rc0
sage-5.0.rc1
sage-5.0
sage-5.1.beta0
sage-5.1.beta1
sage-5.1.beta2
So we should look between 5.0.beta2 and 5.0.beta3, I guess.
