Boost.Regex with GCC broken on Mavericks?

[akimd (Akim Demaille)]

Hi,

First of all, this seems to be strongly related to this ticket: ​http://trac.macports.org/ticket/38984.

On Mavericks (with a fresh install of MacPorts, not a plain upgrade), I have the following behavior which turns out to be very alike the one I had reported in the aforementioned ticket, except that this time GCC is broken, but Clang is not:

{
  boost::regex exp("*");
  boost::regex_match("foo", exp);
  return 0;
}
