 My tests here all work perfectly, running fine if the environment is
 valid, otherwise throwing an exception after main() has started. So it
 would be very helpful to see your code that is failing, and be able to
 test with it here.

 Ok I have prepared a few test cases with two different systems (different
 compilers).
 First of all, the problem occurs only if the programs are linked
 statically and only if codesample 1 is used. Codesample 2 works fine.

 System 1 (Ubuntu 11.10):
 Linux XXX 3.0.0-15-server #25-Ubuntu SMP Mon Jan 2 19:14:55 UTC 2012
 x86_64 x86_64 x86_64 GNU/Linux
 gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3)

 System 2 (Ubuntu 09.10):
 Linux XXX 2.6.31-21-generic #59-Ubuntu SMP Wed Mar 24 07:28:27 UTC 2010
 x86_64 GNU/Linux
 gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu9)

 Boost with version 1.48 was employed and both systems use the same boost
 includes and libs (via nfs shares).

 Codesample 1 (won't work if compiled statically with system 1 and running
 on system 2 with "incorrec LC-ALL"):

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

 int main ( int argc, char *argv[] ) {
   boost::filesystem::path path;
   std::string             filename("readme.txt");
   path = filename;     // this isn't working
 //  path = "readme.txt"; // this isn't working
   std::cout << "OK" << std::endl;
   return 0;
 }
 }}}


 Codesample 2 (works all the time):

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

 int main ( int argc, char *argv[] ) {
   boost::filesystem::path path("readme.txt");
   std::cout << "OK" << std::endl;
   return 0;
 }
 }}}


 Compiling codesample 1 with system 1:[[BR]]
 g++ main.cpp -o test_SYS-1_dyn -L$LIB_PATH -lboost_system
 -lboost_filesystem -I$INCLUDE_PATH[[BR]]
 g++ main.cpp -o test_SYS-1_sta -L$LIB_PATH -lboost_system
 -lboost_filesystem -I$INCLUDE_PATH -static

 Compiling codesample 1 with system 2:[[BR]]
 g++ main.cpp -o test_SYS-2_dyn -L$LIB_PATH -lboost_system
 -lboost_filesystem -I$INCLUDE_PATH[[BR]]
 g++ main.cpp -o test_SYS-2_sta -L$LIB_PATH -lboost_system
 -lboost_filesystem -I$INCLUDE_PATH -static

 Running the programs:

 With system 1: [[BR]]
 and export LC-ALL='C': [[BR]]
 test_SYS-1_dyn:OK [[BR]]
 test_SYS-1_sta:OK [[BR]]
 test_SYS-2_dyn:OK [[BR]]
 test_SYS-2_sta:OK [[BR]]

 and export LC-ALL='en_GB.UTF-8': [[BR]]
 test_SYS-1_dyn:OK [[BR]]
 test_SYS-1_sta:OK [[BR]]
 test_SYS-2_dyn:OK [[BR]]
 test_SYS-2_sta:OK [[BR]]


 With system 2: [[BR]]
 and export LC-ALL='C': [[BR]]
 test_SYS-1_dyn:OK [[BR]]
 test_SYS-1_sta:OK [[BR]]
 test_SYS-2_dyn:OK [[BR]]
 test_SYS-2_sta:OK [[BR]]

 and export LC-ALL='en_GB.UTF-8': [[BR]]
 test_SYS-1_dyn:OK [[BR]]
 test_SYS-1_sta:
 terminate called after throwing an instance of 'std::runtime_error'
   what():  locale::facet::_S_create_c_locale name not valid
 Aborted
 test_SYS-2_dyn:OK [[BR]]
 test_SYS-2_sta:OK [[BR]]


 Thanks,

 Christian
