Comment #6 on issue 1950 by asmeurer: Piecewise((x, 0 < x), (0, Eq(x, 0)), (-x, x < 0))._eval_interval(x, -1, 1) is wrong

Measure zero intervals contribute nothing to an Integral. See the first sentence of http://en.wikipedia.org/wiki/Lebesgue_integral#Basic_theorems_of_the_Lebesgue_integral. The result to that one should be exactly the same as the result to this one (which I agree is a wrong result, but it isn't caused by the oo term):
