It is either a bug of the debugger, or the compiler inlines the function =
in
main() (in a bad way), but i believe it is the first. Consider the code:=0D
 =0D
#include <list>=0D
#include <iostream>=0D
#include <cstdlib>=0D
 =0D
class something=0D
{=0D
 public:=0D
 ~something() { std::cout<<"Hesperia\n"; }=0D
};=0D
 =0D
void f()=0D
{=0D
 using std::list;=0D
 =0D
 list<something> ls(10);=0D
}=0D
 =0D
=0D
int main()=0D
{=0D
 f();=0D
 =0D
 std::system("pause");=0D
 =0D
}=0D
 =0D
 =0D
It produces:=0D

C:\c>temp=0D
