     Type:  Bugs                    |      Status:  new            
Milestone:  To Be Determined        |   Component:  program_options
  Version:  Boost 1.49.0            |    Severity:  Problem        
 Keywords:  g++ lto                 |  
------------------------------------+---------------------------------------
 A minimal example is simply

 {{{
 #include "boost/program_options.hpp"

 int main ( int argC, char* argV[] )
 {
     return 0;
 }
 }}}

 Compiling this using either[[BR]]
 g++ main.cpp -static -flto -std=c++11 -fwhole-program[[BR]]
 or[[BR]]
 g++ main.cpp -static -flto -std=c++11 -fno-use-linker-plugin[[BR]]
 gives a lot of errors:


 `_ZTIN9__gnu_cxx24__concurrence_lock_errorE' referenced in section
 `.text._ZN9__gnu_cxx30__throw_concurrence_lock_errorEv[_ZN9__gnu_cxx30__throw_concurrence_lock_errorEv]'
 of /usr/lib/gcc/x86_64-linux-gnu/4.7/libstdc++.a(eh_alloc.o): defined in
 discarded section
 `.gnu.linkonce.t._ZTIN9__gnu_cxx24__concurrence_lock_errorE'
 of /tmp/ccEoPVoT.o (symbol from plugin)[[BR]]
 ...[[BR]]
 collect2: error: ld returned 1 exit status


 I tried g++4.6 and 4.7. I am not sure if it is a bug within the g++ or
 within boost. If either -static, -flto or -std=c++11 is omited the program
 compiles fine. Only if all three are present the error occours. I am using
 Debian Wheezy.
