#6744: [Assign][GIL] Boost Assign and GIL incompatibility in gcc 4.3.2
-------------------------------+--------------------------------------------
 Reporter:  ATHundt@…          |       Owner:  nesotto
     Type:  Bugs               |      Status:  new    
Milestone:  To Be Determined   |   Component:  assign 
  Version:  Boost 1.49.0       |    Severity:  Problem
 Keywords:  assign gil         |  
-------------------------------+--------------------------------------------
 The following source code compiles under clang 3.1, but fails under gcc
 4.3.2 with boost version 1.46. It doesn't look like there are updates to
 either library in the boost news list since then.

 #include <vector>
 #include <boost/assign/std/vector.hpp> // for 'operator+=()'
 #include <boost/gil/gil_all.hpp>

 int main(int argc, char** argv){
     using namespace boost::assign;
     std::vector<int> values;
     values += 1, 2, 3, 4;

     typedef boost::gil::rgb8_pixel_t pt;
     std::vector<pt> pixValues;
     pixValues += pt(1,2,3),pt(2,3,4);
 }

 -------------------------------------
