I'm trying to manually hook the game overlay onto a process, but I get the following error:
Job 1, './gameoverlayui' terminated by signal SIGSEGV (Address boundary error)

To reproduce:

1. Run steamoverlayui in /steam/ubuntu12_32 with the following command
   ./steamoverlayui -steampid ${pidof steam} -pid ${pidof [game process]}

Apologies if this is a trivial mistake.
