 compile with g++ exeinfo.cpp -lboost_filesystem -lboost_system, everything
 is ok, the output is expected as <the second and fourth lines are the path
 where the binary exists>
 a.out
 /home/hzj-jie/tmp
 a.out
 /home/hzj-jie/tmp

 compile with g++ exeinfo.cpp -lboost_filesystem -lboost_system -static,
 static link with boost, the line 41, which is the constructor of ABC class
 will crash. the call stack is,

 }}}

 according to some basic investigation, the trouble is coming from
 libs/filesystem/src/path.cpp, while the path_locale has not been
 initialized before ABC::ABC() running.
 because of the difference of implementation, in windows, no matter static
 or dynamic link, will not cause crash.
 please kindly let me know if this is by design, or has been fixed in the
 coming release, or if there were some work around.

 thank you in advanced.

 the environment i am now using is,
 Linux hzj-jie-x61t 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08
 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
 gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1)
 but i have tried this on an x86 machine, which has the same experience.
