[Boost-users] [interprocess] file_mapping/mapped_region on empty file throws?

The following appears to throw an interprocess_exception with 
boost_1_44_0 compiled with MSVC8 running on windows XP.

   using namespace boost::interprocess;

   file_mapping  fm("empty.txt", read_only);
   mapped_region mr(         fm, read_only);

Is there a reason I can't just get back a null address and zero size?

I've wrapped this to get back a begin/end range and an empty range is a 
valid condition.

Thanks, Jeff
