Comment (by anonymous):

 Hi,

 I see the same behaviour (std::string::assign segmentation fault after
 calling programs_options::notify() ) when I have the gcc option:

 {{{
 -fno-rtti
 }}}


 {{{
 dwyer_at_bane build]$ g++ --version
 g++ (GCC) 5.3.1 20160406 (Red Hat 5.3.1-6)

 }}}

 Boost: 1.61.0 release version.

 When I remove that command line option, everything works fine.
