I had that problem recently on a Taiwanese frame. Ended up having to cut it out. My procedure was:
* first but a slit in the cup to get better tool purchase - cup is scrap at this point. Did not work. Next get really aggressive.
* slice the end almost down to the treads in a + shape - two cuts 90° apart, using a fiber reinforced cut off wheel in a motor tool (aka Dremel - mine is a 160W Harbor Freight tool, better than what Dremel offers, at a fraction of the price). The ends of these cuts should be as close as practical to the threads without actually cutting into the threads. The + is on the face of the cup, perpendicular to the BB axle.
* widen one of the four slots so that you can get your smallest grinding bit in there.
* using your smallest grinding bit, with the spindle of the tool parallel to the BB axle (axle not installed!!); deepen the wide slot until you can see the thread form along the whole depth of the slot.
* using a sharp screw driver, push the remains of the cup inwards on each side of the wide slot. It will break, where you ground, and pop inwards.
* grab the cup with slip joint pliers or vice grips, crush it, and pull it out.
My situation had severe corrosion around a quarter of the out side of the cup.
The threads were damaged by the corrosion and my efforts, fortunately Wheel Away (Hamilton Ave, Campbell, CA) has the Park Tool to chase the threads and face the BB shell and has very reasonable rates.
