Bug ID: 67703
   Summary: assert after placement new
   Product: gcc
   Version: 5.2.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: piotrekpad at gmail dot com
  Target Milestone: ---

Hi,
This code is is c++11 valid:

#include 
#include 
struct A {
  virtual void foo();
};

struct B  : A{ 
  void foo();
};
void f() {
  A *a = new A;
  a->foo();
  A* b = new() B;
  assert(a == b);
  b->foo();
  new(b) A;
  a->foo();
}

but when I compile it with g++ 5.1 or 5.2 it fails on assert (checked on
https://gcc.godbolt.org/)
