std::string operator+() memory leak?

Question

I\'m quite worry because I wrote a little application and it seems that there is a memory leak if I believe valgrind (What I actually do):

==9321== 251 bytes in

To quote Valgrind FAQ

With GCC 2.91, 2.95, 3.0 and 3.1, compile all source using the STL with -D__USE_MALLOC. Beware! This was removed from GCC starting with version 3.3.

With GCC 3.2.2 and later, you should export the environment variable GLIBCPP_FORCE_NEW before running your program.

With GCC 3.4 and later, that variable has changed name to GLIBCXX_FORCE_NEW.
