--- Comment #3 from jonne <gcc at zutt dot org> ---
Read somewhere that I need to do this to make gdb work on Sierra. Not sure what
it all means...
$ cat ~/.gdbinit
set startup-with-shell off
After doing that, I get a different result running gdb.
$ sudo /usr/local/Cellar/gdb/7.12.1/bin/gdb ./a.out
GNU gdb (GDB) 7.12.1

done.
(gdb) run
