#11792: Boost convert will dereference empty strings iterators
-----------------------+------------------------------
 Reporter:  anonymous  |       Type:  Bugs
   Status:  new        |  Milestone:  To Be Determined
Component:  None       |    Version:  Boost 1.59.0
 Severity:  Problem    |   Keywords:
-----------------------+------------------------------
 The dereference can be found in `boost/convert/base.hpp`:`to_str_` (line
 108 in boost 1.59.0).
 {{{
         /**/ if (skipws_) for (; std::isspace(*range.begin()); ++range);
         else if (std::isspace(*range.begin())) return;
 }}}

 `range` should be checked to see if it is empty before it is dereferenced.
