#7175: Rev 74766 breaks unordered_map on gcc 3.4
-----------------------------------+----------------------------------------
 Reporter:  luc_j_bourhis@…        |       Owner:  danieljames
     Type:  Bugs                   |      Status:  new        
Milestone:  To Be Determined       |   Component:  unordered  
  Version:  Boost 1.50.0           |    Severity:  Problem    
 Keywords:                         |  
-----------------------------------+----------------------------------------
 I was initially confronted to that bug with 1.50 and then I pinpointed the
 first bad rev using git bisect. Here is how to reproduce the problem:

 ~> gcc --version
 gcc (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
 ...

 ~> cat regress_unordered.cpp
 #include <boost/unordered_map.hpp>
 #include <iostream>

 int main() {
       boost::unordered_map<std::string, std::size_t> counts;
       counts["one"]++;
       std::cout << counts["one"] << std::endl;
 }

 ~> g++ -c regress_unordered.cpp -I/path/to/boost
