I'm guessing you switch the toolset to be qcc. In that case, the libboost-filesystem.so was built against libcpp 
(Dinkumware C++ library) and when you link with the gcc driver (ntox86-g++-3.3.5) you link against the GNU C++ library 
so you end up linking against both C++ libraries.

If you built Boost with qcc, you should be using qcc for your project. If you built Boost with gcc, you should be using 
the gcc driver for your project.

For example:

# ntox86-g++-3.3.5 -I/usr/local/include/boost-1_34_1 boost.cc  -L/usr/local/lib -lboost_filesystem-d
# ./a.out
Memory fault (core dumped)
# qcc -V3.3.5,gcc_ntox86 -I/usr/local/include/boost-1_34_1 boost.cc  -L/usr/local/lib -lboost_filesystem-d
# ./a.out
 File does not exist
# touch /bbb.xml   
# ./a.out
 File exists
