Hi All,
I have a simple program
/*************************/
#include <iostream>
#include <string>
main()
{
std::string test;
test ="abc";
std::string *test2 = new std::string("abc");
delete test2;
}
/******************************************/
Now I am running valgrind over it
valgrind --tool=massif ./a.out
on ms_print
it is howing output as
/****************************************
n time(i) total(B) useful-heap(B) extra-heap(B) stacks(B)

/*********************
Why valgrind is showing stack variables in heap. Any idea.
