Error when integrating absolute value

Please read the whole warning. The problem comes from singulatiries in sign(cos(variable_name)) inside the antiderivative.

It's not purely numeric, because you must compute the inner integral symbolically. In fact, it's the same problem, fixing singularity checks for the first integral returns 9 for the second one.

BTW, if you want to help us fixing bugs, please post plain text commandlines that I can easily paste in the emulator, pictures can not be pasted (and they waste Internet bandwidth...).
