 Hi,

 I came across unexpectedly on the problem with
 boost::filesystem::remove_all and widechar-strings on the Linux and GCC.

 My compilation environment:
  - Fedora7;
  - gcc version 4.1.2 20070925 (Red Hat 4.1.2-27);
  - boost 1.34.1.

 The following test program leads segmentation fault at the line marked
 with "Boom!!!" comment.


 {{{
 #include <iostream>
 #include <boost/filesystem.hpp>

 int main( int argc, char const * argv[] )
 {
     namespace fs = boost::filesystem;

     // This doesn't work
     fs::wpath tempRoot = L"./temp1/temp2";
     fs::wpath root = L"./temp1";
     // This works.
     //fs::path tempRoot = "./temp1/temp2";
     //fs::path root = "./temp1";

     try
     {
         std::cerr << "--- boost filesystem test --- " << std::endl;
         bool bRes = fs::create_directories( tempRoot );
         std::cerr << "bRes: " << bRes << std::endl;
         if ( bRes )
         {
             unsigned long n = fs::remove_all( root ); // <- Boom!!!
             std::cerr << "n: " << n << std::endl;
         }
     }
     catch ( std::exception const & ex )
     {
         std::cerr << "Exception: " << ex.what() << std::endl;
     }

     return 0;
 }
 }}}


 The source was compiled with following options:
 g++ -g boost_fs.cpp -I/usr/local/include/boost-1_34_1 -lboost_filesystem-
 gcc41-1_34_1 -o boost_fs.exe

 Note, the problem arises if Unicode string is used.
