iOS compile: XCode throws "Exit Code 1"

So a few months back I tested to see if I could publish something to the iPad and after four or five tries finally found the settings needed to get it running smoothly (this involves three computers: one to code, one to turn it into XCode, and one to finally turn that XCode into an ipa, as the second machine isn't up to date on it's XCode version, which needs a newer OSX).

Anyway, larger project, wanted to make sure that it'd run smoothly on the iPad before it gets developed too far, so that optimizations can be made if necessary.

Compile fails in the last step with an "Exit Code 1" and no explanation. No amount of googling brings me any closer to fixing the problem. So I look back at the older project that was used as a test, copy all of the settings over (SDK version, target iOS version, etc. etc). No dice

Compile up the test project. Success.

Fine, I say, I export all of the new project's assets and import them into the old project. Things come through just fine, just some missing textures; good enough for a test.

Exit Code 1.

So clearly there's something inside the project itself which is causing the error, not the settings, the ipad, the three machines involved, developer key, or the developer certificate.
