 Reporter:  anonymous     |       Owner:  vladimir_prus  
     Type:  Bugs          |      Status:  new            
Milestone:  Boost 1.43.0  |   Component:  program_options
  Version:  Boost 1.42.0  |    Severity:  Problem        
 Keywords:                |  
--------------------------+-------------------------------------------------
 Given the code in libs/program_options/src/options_description.cpp:


 {{{
 option_description::
 option_description(const char* name,
                    const value_semantic* s,
                    const char* description)
 : m_description(description), m_value_semantic(s)
 {
     this->set_name(name);
 }
 }}}

 s leaks in case if initialization of m_description throws.

 The simplest cure is to make option::description::m_value_semantic member
 to be before all other members.
