Curly braces are special in regexps: they must be paired.  You
probably meant this:

   ".*\\{"

(It is also probable that, if you really did mean special curly
braces, then putting them after the asterisk quantifier is a bad
idea.)

The abort was probably caused by an unhandled exception.  Try catching
all exceptions, e.g.:

    try
    {
        // do whatever
    }
    catch ( const std::exception & e )
    {
        std::clog << "caught standard exception: " << e.what() << std::endl;
    }
    catch ( const std::string & s )
    {
        std::clog << "caught c++ string exception: " << s << std::endl;
    }
    catch ( const char * s )
    {
        std::clog << "caught C string exception: " << s << std::endl;
    }
    catch ( ... )
    {
        std::clog << "caught unexpected exception" << std::endl;
    }

Hope this helps.

p.s. Boost 1.26?  Really?  That's *ancient*...
