It is probably an OS X only crash.

Emacs won't write the file unless if server-use-tcp is enabled. Customize
it, enable server-use-tcp (set to true), save for future sessions. Restart
emacs. Launch server. If the folder doesn't exist, Emacs will create it and
assign 700 perms.

I've reproduced with a vanilla configuration of Emacs to rule out the
possibility it is a conflict with some other extension I've installed.
