10388,null character at end of string from filesystem::temp_directory_path,anonymous,Beman Dawes,"The null character at end of string causes very interesting bugs that are hard to debug.

Workaround we learned to use is .c_str():

   filesystem::path temp_path = filesystem::temp_directory_path( ec ).c_str();

Cause of bug:
GetTempPathW(0, 0) returns the size of buffer enought to contain the path, but is might be bigger than (path length + 1). (It rarely happens, but happens.)
However the function filesystem::temp_directory_path expects it to be exactly (path length + 1).

Solution:
replace lines
   buf.pop_back();
   path p(buf.begin(), buf.end());
with
   path p(buf.begin());",Bugs,closed,To Be Determined,filesystem,Boost 1.57.0,Problem,fixed,,
