Hi there,
I use boost version 1.49.0. I meet a memory leak for below sentences:
boost::filesystem::path tmp = input.stem();
string strDir = tmp.normalize().string();
Valgrind report memory leak as below:

(path.hpp:430)
Because my program need run thousands of time and very sensitive for the
memory leak. Could anyone help to suggest one way to avoid such memory leak?
Thanks a lot!
Best wishes,
