This appears to be the createdb program itself crashing, not the server.
That cuts down the alternatives quite a lot, because createdb isn't
much; it basically just tries to connect via libpq and send a CREATE
DATABASE command to the server. My first thought is that you have a
corrupt libpq.so, or one that is incompatible with your createdb
executable. You could check some of the more obvious causes by
seeing what "file" and "otool -L" have to say about createdb and
libpq.so.
