#6948: Boost::spirit::karma generator bug
 Reporter: yaoyuan1216@… | Owner: djowel

Milestone: To Be Determined | Component: spirit
  Version: Boost 1.49.0 | Severity: Problem
 Keywords: |
 I wanna save a generator so that I can call it anytime without writing
 duplicate codes. Here is my code:


 //auto par = '{' << -(boost::spirit::karma::int_ % ',') << '}';//This
 would lead error!
 int main(){
         using namespace std;
         namespace karma = boost::spirit::karma;
         list<int> l{1, 2, 4};
         auto par = '{' << -(boost::spirit::karma::int_ % ',') <<
 '}';//This would not!
         cout<<karma::format(par, l)<<endl;
         return 0;

 When I define par out of a functint would leads to runtime error. Does I
 used it generator in a wrong way or it is a bug?
 GCC version 4.6.3
