#12017: Segfault with Boost program_options 1.60 debug libraries on OSX

 Hi,

 I'm using Boost 1.60.0_1 (installed from Brew) and am trying to compile
 the following file:


 {{{
 //mytest.cpp:
 #include <boost/program_options.hpp>
 #include <string>

 namespace po = boost::program_options;

 int main(int argc, char *argv[])
 {
     po::variables_map vm;
     po::options_description desc;

     desc.add_options()
     ("test,t", po::value<std::string>()->default_value("something"))
     ;

     po::store(po::parse_command_line(argc, argv, desc), vm);
     po::notify(vm);
     return 0;
 }
 }}}

 I'm using CMake to compile. When compiling in Release mode, everything
 works fine. But when compiling in Debug mode, i get a segfault in the
 store() function when I run the program without the -t option:

 {{{

 }}}

 I noticed this happens only if the binary is linked with the static debug
 libraries, i.e libboost_program_options-d.a and libboost_program_options-
 mt-d.a. To reproduce without CMake:

 {{{
 $  c++ mytest.cpp -I/usr/local/include
 /usr/local/lib/libboost_program_options-d.a -o mytest && ./mytest
 [1]    83707 segmentation fault  ./mytest

 $  c++ mytest.cpp -DDEBUG -I/usr/local/include
 /usr/local/lib/libboost_program_options-d.a -o mytest && ./mytest
 [1]    83709 segmentation fault  ./mytest
 }}}

 It crashes only when run without the -t argument; If I provide it, it
 works fine:
 {{{
 $ ./mytest -t test
 }}}

 It does not crash when linked statically with a non-debug library:
 {{{
 $ c++ mytest.cpp -DDEBUG -I/usr/local/include
 /usr/local/lib/libboost_program_options.a -o mytest && ./mytest
 $ c++ mytest.cpp -DDEBUG -I/usr/local/include /usr/local/lib
 /libboost_program_options-mt.a -o mytest && ./mytest
 }}}

 Or when linked dynamically with one of the shared libraries:
 {{{
 $ c++ mytest.cpp -I/usr/local/include
 /usr/local/opt/boost/lib/libboost_program_options.dylib -o mytest &&
 ./mytest
 $ c++ mytest.cpp -I/usr/local/include /usr/local/opt/boost/lib
 /libboost_program_options-mt.dylib -o mytest && ./mytest
 }}}

 The only workaround I found in order to compile a working debug binary
 with CMake is to use -DBoost_USE_STATIC_RUNTIME=ON because for some reason
 it tells the compiler to link with the shared library).
