[Boost-users] What would happen if boost::shared_ptr is reset to an address in the stack

Hi,

The following program runs well in my system. However, if I change 1
to 0, it will terminate at the line with "delete". Does this mean that
boost::shared_ptr can tell if the pointer is from the stack or the
heap and does different things based on where the pointer is from?

Thanks,
Peng

#include <iostream>
#include <boost/shared_ptr.hpp>

int main() {
#if 1//try change this to 0
  int a[100];
  boost::shared_ptr<int> p(a);
  std::cout << std::endl;
#else
  int a[100];
  delete a; // would terminate here
  std::cout << std::endl;
#endif
}
