#6201: managed_shared_memory construstor crashes

     Type:  Bugs                                    |      Status:  new         
Milestone:  To Be Determined                        |   Component:  interprocess
  Version:  Boost 1.48.0                            |    Severity:  Problem     
 Keywords:  managed_shared_memory gcc optimization  |  
----------------------------------------------------+-----------------------
 The following code crashes with segmentation fault when compiled with the
 symbol -DNDEBUG and optimization -O1 or -O2 or -O3 using gcc 4.6.1 from
 ubuntu oneiric.

 {{{
 int main(int argc, char** argv)
 {
     namespace bi = boost::interprocess;
     const char* name = "foobar";
     bi::shared_memory_object::remove(name);
     bi::managed_shared_memory segment(bi::create_only, name, 10 * 1024 *
 1024);
 }
 }}}

 Without the NDEGUB symbol it always works. With NDEBUG it works only with
 -O0.

 The call stack obtained with -O1 -g -DNDEBUG is the following:
