It's not a bug. Attempting to manually summon two of the same boss while one is still alive (I believe it applies to all of them, not just the Eater of Worlds) results in instantaneous death. I'd guess its to prevent uberfarming, or so you can't summon fifteen of them in multiplayer and then let them trash everyone else's bases. It might, however, be possible to summon multiple different bosses at the same time (i.e. Eater + Eye) if you're looking for a challenge, though I'd test that first.
