From https://groups.google.com/forum/#!topic/sage-support/L75JgocZc3I verbatim (but the syntax for Maxima should be very similar here):

a,b=var('a b');
assume(4*b^2-4*a^2<0);
assume((b-a)*(b+a)<0);
integrate(1/(a-b*sin(x)),x,-oo,oo)

It complains and asks whether (b-a)*(b+a) is negative or positive.
