AC compressor uses a clutch pulley I believe, so when the AC is turned on the pulley is locked to the compressor and drives it.. When turned off, the pulley freely rotates.
If the compressor is failing and causing more load on the belt/crank-pulley you might get some funny running of the engine, however I'd imagine the ribbed belt would have slipped before causing the engine to stall...
At any rate, if the compressor is borked then there's a risk that it'll sieze and cause the aux-belt to snap.. These have been known to take out the timing belt when they fail (rubber fragments getting inside the timing cover)...
Cheapest solution might just be to find a shorter ribbed belt and bypass the AC compressor all together if you don't need it...
