String and std::string

I've been unable to confirm this. I tried the attached
program (compiled with gcc -lstdc++ stringleak.cpp)
and got the following results from top: 

PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM  
  648 alex      14   0   556  556   416 R    56.2  0.2
  

TIME COMMAND
3:02 a.out

Am I correct in concluding that std::string::c_str()
does not leak? I'm interested as I use c_str() a fair
amount for interfacing C++ with C (I believe that was
what it was designed for, but I'm only guessing).

Regards,
Alex
