 boost build
 {{{
 D:\LIBS\boost_1_60_0>b2 -d+2 --debug-building link=static threading=multi
 runtime-link=shared stage
 }}}

 I've used -d+2 and --debug-building to see the used compilation flags.

 Extract from the boost building output
 {{{

 }}}

 For this test, I used the command line and exactly the same flags as used
 by boost.
 I've copied the generated b2_msvc_14.0_vcvarsall_x86.cmd to have the same
 environment: path, include and libpath.

 Build the test app:
 {{{
 call b2_msvc_14.0_vcvarsall_x86.cmd
 cl "LocaleNumPunct.cpp" /Zm800 -nologo -DNDEBUG -TP /O2 /Ob2 /W3 /GR /MD

 /LIBPATH:"D:\LIBS\boost_1_60_0\stage\lib"
 }}}

 LocaleNumPunct.cpp
 {{{#!c++
 #include <locale>
 #include <string>
 #include <iostream>

 #include "boost/locale.hpp"

 int main()
 {
   using namespace std;

   float v = 2.14f;

   // Use std locale to format a float

   auto stdLocale = std::locale("German_germany");
   cout.imbue(stdLocale);
   cout << "std locale " << v << endl;

   auto& stdNumPunct = std::use_facet<std::numpunct<char>>(stdLocale);
   cout << "std locale decimal_point " << stdNumPunct.decimal_point() <<
 endl;

   cout << "std locale num_put ";
   auto& stdFacet = std::use_facet<std::num_put<char>>(stdLocale);
   stdFacet.put(cout, cout, '0', v);
   cout << endl;

   // Use boost locale to format a float

   boost::locale::generator gen;
   auto boostLocale = gen("de_DE.UTF-8");
   cout.imbue(boostLocale);

   cout << "boost locale " << boost::locale::as::number << v << endl;

   auto& boostNumPunct = std::use_facet<std::numpunct<char>>(boostLocale);
   cout << "boost locale decimal_point " << boostNumPunct.decimal_point()
 << endl;

   cout << "boost locale num_put ";
   auto& boostFacet = std::use_facet<std::num_put<char>>(boostLocale);
   boostFacet.put(cout, cout, '0', v);
   cout << endl;

   return 0;
 }
 }}}

 LocaleNumPunct.exe output:
 {{{
 std locale 2,14
 std locale decimal_point ,
 std locale num_put 2,14
 boost locale 2.14
 boost locale decimal_point ,
 boost locale num_put 2.14
 }}}


 > Also small question: does it happen with different version of MSVC?

 Unfortunatelly, I do not have the previous MSVC at hand.
