Comment (by Braden McDaniel <braden@…>):

 That's consistent with what I've seen: I was not able to reproduce the
 problem when building without the `-stdlib=libc++` flag. Unfortunately,
 the version of GNU libstdc++ available on Darwin is rather dated and thus
 not perceived as a path forward for new C++ development.

 Here is a backtrace from the throw point:

 {{{
 #0  0x00007fff8457254d in __cxa_throw ()
 #1  0x000000010000658c in boost::throw_exception<boost::bad_lexical_cast>

 lexical_cast.hpp:2300

 }}}

 If you'd like me to try to get one from some other point in the code, let
 me know.
