In order to start the app properly pgsql must be running. The issue here is that node@3 segfaults instead of giving a meaningful error.

[yoshuawuyts]

Hm, apparently it also fails even if pgsql is running. Might be due to binaries compiled on 0.12 not working on 3.3.

Yes, you'll need to re-compile any addons if you switch between any of node 0.10, node 0.12, or any major io.js version (1.x, 2.x, 3.x).

@mscdex yeah, I figured. Think this issue is best closed (can't think of an easy fix), but I do think that it'd be nice to think of a better way to signal to a user why the code segfaulted.

Perhaps a stack trace of some sorts? Though I'm not sure that's possible, I assume it'd be implemented already if it was.

Maybe a way to check if the deps that are being run were compiled with a certain node version? I'm not sure.
