https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217200 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: freebsd-bugs@FreeBSD.org Reporter: dim@FreeBSD.org >From https://bugs.llvm.org/show_bug.cgi?id=3D32002: 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. Bu= t it should initialize it to zero, as if "new (ptr) int()" is called, where ptr = is the address of allocated memory. --=20 You are receiving this mail because: You are the assignee for the bug.=
