Bit-perfect AAC/MP3/etc decoding?, Is it an issue?

Sorry if this is easily answered elsewhere.

My question is that in a comparison of lossy-format decoders between, let's say, iTunes and Foobar and Winamp, will the output (edit: of a single source file) vary between decoding implementations?

Or is it that once a decoder follows a specified format, all output is equal assuming there are no bugs?

Unlike encoding, I believe all decoders are supposed to be the same.

The decoder has a lot simpler task of decoding & reconstructing a wavefrom from whatever data is present. The encoder has to decide what data to throw-away.
