Comment(by dylukes):

 More information and some clarifications:

 - I can confirm updating to 10.8 DP2, or Xcode 4.4 DP2 do not fix it.
 Individually or together.
 - This manifests in the x86_64 AND i386 architectures.
 - There is an existing issue with binaries compiled on 10.8 not running on
 10.7 or previous. This has been reported to Apple, and is mirrored here:
