Comment:

 On further review, this is a C++ standards issue and not a Boost.Format
 concern.

 See:

 http://cplusplus.github.io/LWG/lwg-defects.html#2221

 A workaround is to define your own std::ostream operator for your program
 to work with a nullptr - it is not the responsibility of Boost.Format to
 do this for a native type.  Doing so would lead to compatibility issues
 later if the standard changes requiring libraries to implement it - it
 would become ambiguous again.

 Additional discussion can be found on stack overflow which has suggestions
 for a workaround:
