 I'm working on upgrading the Symphony Homebrew formula to 5.5.7. It
 compiles with gcc-4.2 but gcc-4.8 leads to seg faults. I ran the simple
 test mentioned in the README through Valgrind:

 }}}

 The dependencies weren't installed with Homebrew; Symphony built
 everything it needed (`CoinUtils`, etc.)

 Note that if I `make test`, I get similar seg faults. This is on OSX
 10.8.5.
