Attached program segfaults.

I compiled erlang myself, so I could have done something wrong, but it
seems to work otherwise.

How I compiled it:
  ./configure --prefix=/home/jdavis/install/otp \
              --enable-dirty-schedulers
  make && make install

System:
  $ uname -a
  Linux jdavis 3.11.0-15-generic #23-Ubuntu SMP
  Mon Dec 9 18:17:04 UTC  2013 x86_64 x86_64 x86_64 GNU/Linux
  $ cat /etc/lsb-release

Erlang:
  $ /home/jdavis/install/otp/bin/erl
  Erlang/OTP 17 [RELEASE CANDIDATE 1] [erts-6.0] [source] [64-bit]
