There is a no_except flag that can be passed the regex constructor/assign
methods to disable throwing of exceptions:

boost::regex e("bad**string", boost::regex_constants::perl |

    std::cout << "oops" << std::endl;

However, I notice that I removed all mention of this from the docs when I
updated the interface to match the TR1 spec. It's non-the-less still
supported however.
