The crush compiler indeed has minimal error handling

  if (!info.full) {
    int cpos = info.stop - start;
    //out << "cpos " << cpos << std::endl;
    //out << " linemap " << line_pos << std::endl;
    assert(!line_pos.empty());
    map<int,int>::iterator p = line_pos.upper_bound(cpos);
    if (p != line_pos.begin())
      --p;
    int line = p->second;
    int pos = cpos - p->first;
    err << infn << ":" << line //<< ":" << (pos+1)
    << " error: parse error at '" << line_val[line].substr(pos) << "'" << std::endl;
    return -1;
  }
