STL-String memory leak?

Hello developers !
I've got some memory-problems using stl-strings.
I'm running RH6.1 kernel 2.2.12 with g++ 2.95.1.
Please take a look at the following short piece of code:
------------------------------------------------
#include <vector>
#include <string>
int main()
{
vector<string *> myvec;
for(int i=0; i<50; i++)
myvec.push_back(new string("aaa"));
sleep(10);
vector<string *>::iterator eraser_it;
eraser_it = myvec.end();
while(!myvec.empty())
{
eraser_it--;
if((*eraser_it) != NULL)
delete(*eraser_it);
myvec.pop_back();
}
sleep(10);
exit(0);
}
--------------------------------------------------
The programm should clear all memory allocated by
the "new" statement.
When I watch it with "ps axu" and take a look at its memory
consumption - no memory is freed.
My questions are:
Can I really measure the memory consumption with ps ?
Did I make a basic mistake ?
Or is this really a problem with the memory-handling in
the string-class ?
Thank you,
Gero Krueger
