Bug introduced in 9.0 and fixed in 10.1
I am trying to run the following integral in version 9.0, but it fails:
Integrate[
2 I (-1 +
x) ((-8 + 12 x - 6 mπ^2 x - 2 mπ^2 x^2 -
4 x^3)/((1 - x)^2 +
mπ^2 x) + ((4 - 2 x + 4 mπ^2 x - 8 x^2 +
6 mπ^2 x^2 + 6 x^3) Log[
1/((1 - x)^2 + mπ^2 x)])/((1 - x)^2 + mπ^2 x)), {x, 0,
1}, Assumptions -> mπ > 0 && mπ < .1]
Version 9.0.1:
But in version 8.0, it works:
Is this a bug, or is the integral really non-convergent? What's a possible workaround, since I don't have easy v8 access?
