Bug ID: 217200
Summary: std::make_shared does not perform zero initialization
Product: Base System
Version: 10.3-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: misc
Assignee: [email protected]
Reporter: [email protected]
>From https://bugs.llvm.org/show_bug.cgi?id=32002:
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.
