Bug ID: 32002
Summary: std::make_shared does not perform zero initialization
Product: libc++
Version: unspecified
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: [email protected]
Reporter: [email protected]

On FreeBSD 10.3, the following program displays "123", but "0" is expected:
#include <memory>
#include <iostream>
int main()
{
std::make_shared<int>(123);
std::cout << *std::make_shared<int>();
return 0;
}
The second std::make_shared reuses the piece of memory of the first one. But it
should initialize it to zero, as if "new (ptr) int()" is called, where ptr is
the address of allocated memory.
