#6690: access violation using global path object

 Reporter:  Claudio Bley      |       Owner:  bemandawes
     Type:  Bugs              |      Status:  new       
Milestone:  To Be Determined  |   Component:  filesystem
  Version:  Boost 1.49.0      |    Severity:  Regression
 Keywords:                    |

 I think this is an instance of "static initialization order fiasco".

 The following code crashes with "Access violation reading location
 0x00000000".
 {{{
 #!cpp
 #include <boost/filesystem.hpp>
 #include <iostream>

 const boost::filesystem::path p("test");

 int main(int argc, char *argv[])
 {
   std::cout << p << std::endl;
 }
 }}}
 This is caused by ```codecvt_facet``` not being initialised on its first
 use. Call Stack:

 {{{
 fspath.exe!std::codecvt<wchar_t,char,int>::in(int & _State, const char *
 _First1, const char * _Last1, const char * & _Mid1, wchar_t * _First2,
 wchar_t * _Last2, wchar_t * & _Mid2)  Line 1521 + 0x1f bytes    C++
 fspath.exe!`anonymous namespace'::convert_aux(const char * from, const
 char * from_end, wchar_t * to, wchar_t * to_end,
 std::basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t>
 > & target, const std::codecvt<wchar_t,char,int> & cvt)  Line 84 + 0x24
 bytes       C++
 fspath.exe!boost::filesystem3::path_traits::convert(const char * from,
 const char * from_end,
 std::basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t>

 C++

 std::basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t>
 > & to, const std::codecvt<wchar_t,char,int> & cvt)  Line 174 + 0x60 bytes
 C++
 fspath.exe!boost::filesystem3::path::path<char const [5]>(const char [5]&
 source, void * __formal)  Line 135 + 0x23 bytes       C++
 }}}

 this == 0x00000000

 Compiled with ```cl /EHsc /DEBUG /Zi /D _DEBUG /MTd
 /I%localappdata%\boost\boost_1_49 fspath.cpp /link
 /libpath:%localappdata%\boost\boost_1_49\lib```.
