Comment (by anonymous):

 Hi things got worse with this error. I beleive this worked with 1.63.

 Config:

 boost-1.64.0, vc14, x64, debug, static lib, statically linked runtime

 Error:

 {{{
 Exception thrown: read access violation.

 this->_Ptr->_Facetvec was 0x111011101110111.

 If there is a handler for this exception, the program may be safely
 continued.
 }}}


 Code:

 {{{
 class Alma
 {
 public:
         ~Alma() { std::cout <<
 boost::filesystem::path("c:\\alma.txt").string() << std::endl; }
 };

 static Alma a;

 int main(int argc, char* argv[])
 {
         return 0;
 }
 }}}
