Have you tried running it separately (i.e. "dub build" + "./vibe-test")?
Maybe that gives a clue.

If it still crashes without an error message, running with GDB should
point to the source of error (if exit code -11 indicates a segmentation
fault here).

BTW, I tried the same program on 10.7.4 and it didn't crash.
